It really depends on what your preferences are game wise. I'm very easy going when it comes to giving an opinion on a game; unless it's absolute dross (like that buttons game on Steam; that said it is a four person party game). My early memories of PC games are from the late 80's, so when I see and play most games now, I think I'm living in a utopian future. I love virtually everything. I think many of the games I play are beautiful and pure art.
So....... from your post I presume you don't have Section 8, First Templar, Insecticide, Legendary, Dream Pinball, and Disciples III Resurrection? In my opinion, it's worth paying the price for just the pinball game let alone the rest of these games, (You'd pay £7.99 for just that game on Steam right now, that's more than double the asking price for the whole lot)
With respect to my views on the games you don't own.....................
Section 8:
I definitely consider Section 8 under-rated, though it does have a metacrit score of 72, which isn't poor. (I've played games with Metacrit scores of around 40 and thought them excellent (e.g.Damnation - the main complaint with that game from the majority were the controls, which were very confusing at first. The game was one where you had to clinnb great heights using various key combinations to get from A to B, that were even more complicated than Mirrors Edge; however, once you got used to them, the game was actually a lot of fun). If you like any of the Unreal Tournament games you'll love Section 8. it's similar to the UT games with a sci fi feel, arena battles etc plus the ability to jump using special flight gear to get yourself out of trouble and to jump onto high buildings. I've not played it in a while, but throughly enjoyed the time I have played, both single player against bots and with my son in multiplayer. If you really like it you can get the sequel called Section 8: Prejudice from Steam for £9.99. It'll probably be in the summer sale for at least 75% off as it's been out since May 2011.

First Templar:
First Templar has a Metacrit score of 57, but I think it was easily worth more. It's a third person action adventure, with reasonable graphics (maybe considered a little dated by today's standards, especially the NPC's and the two characters you control. The environments look better. Turn the heat up and sprinkle some sand on the floor and you'll feel like you're in the Middle East, lol. I enjoyed playing the game.
It's yet another game I think was worth more than what many gave it. But it was released at a time when there was a lot going on in the game world. Skyrim was only 6 months away (lol). If you like medieval style games, this won't disappoint. it's not Assassins Creed, but its has it's own interesting combat style. Very playable (IMO). You can see a preview of game play HERE

Legendary:
Legendary is another game with an average Metacritic score (50). And again I thought it was worth more. I do remember there being bugs, but I throughly enjoyed playing this end of the world apocalyptic game. With weird and wonderful monsters set in a backdrop of London and New York. I've purchased 3 copies of this, a DVD version when it was first released, then two Steam copies, one for me and one for my son. I'll probably pick up bundle Stars so that I can give the copy to my daughter. She loves mythical beasts such as the Griffon etc. I already have all of the games in the bundle, but will share them between my kids. They are always happy to receive more games. :) You can see a video of gameplay showing the beginning of the game I havn't played it in ages, but I seem to remember you start with a pistol. :) HERE
-----------------------------------------------------
Dream Pinball 3D:
Dream Pinball, well what can I say about this. It's pinball....... It's not as pretty as the latest Pinball release on Steam Pinball FX (with 24 tables), but its still a great game. It's got six tables, called Amber Moon, Aquatic, Knights Tournament, Monsters, Spinning Rotors and Dino Wars. You can see all of the tables in action in this 2 minute video HERE
-----------------------------------------------------
Insecticide Part 1:
Of all of the games in the bundle, Insecticide is the only one I've not got around to playing yet (I checked it over, but had other games I wanted to play first.. it sort of got lost in the long list of games (I can never find games when I want them - well, at least those I've forgotten the name of, but I know what the game is in my head, just the name excapes me, lol) . I purchased Inmsecticide ages ago, and is one of the older games, released in 2008 (around the same time as legendary. It's got cartoon style graphics and a third person perspective. If you like the comedy apects of some of Telltale games titles you'll like this one as well, some of the dialogue is funny (this is by SouthPeak games I think). you can see a video of game play HERE
-----------------------------------------------------
Disciples III: Resurrection:
I think Disciples III Resurrection fell down simply because it was released a few weeks before Skyrim. It didn't stand a chance really, but, if you like strategy games that look a bit like a cross between all of the RPG's of late, you'll like Disciples III Resurrection. I've enjoyed what little game play time I've managed since buying it. It got a metacirt score of 63. You can see a video of game play HERE
-----------------------------------------------------
Imperium Romanum:
If you like city builing games Imperium Romanum is another game you should get. It's even got the arena featured in Ben Hur and there's strategy elements. It's not as good as the Total War series (strategy wise), but the city building elements, add to the overall gaming experience.
Imperium Romanum is another game with a relatively poor 63 metacrit score. You can see a video of game play showing all of the elements of the game HERE
-----------------------------------------------------
Overall, even with the titles you've already got, I think this bundle is a fantastic bargain.
I just wish I could have held off purchasing most of these titles at full price. There's a wide range of game types in the bundle, so, even if you found a couple of them not to your liking, the rest would compensate. Considering I paid full price for all of these games (total cost around £500, the price of this bundle seems like a steal.
