There are some excellent games in this bundle. When I first played Shattered Horizons on its release a couple of years ago, it almost satisfied one of my childhood ambitions of going into space. You get a real feel of floating in space with this game. Coupled with the excellent graphics, this is one of the better game sin the bundle (IMO) you do need at least a DX 10 graphics card and Vista and above OS (you won't be able to play it on an XP operating system).
If you ever played and enjoyed Unreal tournament then you'll like Section 8. Game play is very similar though not as colorful. Sniper Ghost warrior is one of the best sniper games around. The bullet physics are excellent and, when you get ahead shot it all goes into slo- mo. :) Cool effects.
Dino D Day is a waste of time these days. It's a multiplayer game, but you'll be lucky if yo find anyone on line to play it. If you can get several friends to buy the bundle as well and get together, it can be fun, but there are much better shooters. If you want to fight monsters then Legendary should do the trick. Underrated at the time of release, I personally though it was a very enjoyable game. As for the ship, I've still got two copies in my Steam inventory and have only played it for a short time. Didn't enjoy it at all.
For less than $3, four of the games are amazing value (Shattered Horizon, Sniper: Ghost Warrior, Section 8 and Legendary). I'd pay ten time as much for those games if I had to buy them again.
