Fileplanets direct to Drive have got several games on special offer due to it’s fifth anniversary. You can get all the following games for £5 ($7.50) each. Most in my opinion are brilliant bargains especially the first three. I wrote a lot more detail initially, but forgot to add a title when i posted it, so you can guess what happened - yeah I lost everything, so it's a bare bones post with just a video for each game and some images. no written details of each game. sorry. You should be able to get demos for all of the games from Gamershell. They hold a massive list of demos of virtually all games that have been released over the past several years. The X-COM bundle, which includes three games is the oldest set of games. Warhammer Dawn of War includes the expansion packs. I decided to use smaller than normal images because of the number I've posted.

I'm not sure whether you need to subscribe to be able to use the Direct to Drive facility. I have a paid for subscription so am always logged on when I purchase games via Direct to Drive. There is a free subscription, but the downloads tend to be a lot slower than a paid subscription, which is the norm for most download sites. Some of fileplanets games automatically install to the Steam client.
It is always worth checking out Direct to Drive on a weekly basis because they have deals similar to Steam every week.
