F.E.A.R.: 2º play through. Really creepy. It deserves its name. I must admit, the first time I finished this game, it was about 3:00 pm and I wasn't able to sleep that day. The game is a little repetitive, even for a shooter, mostly for the fact that almost all the enemies are the same, since they are clones. But, IMO, it has a interesting plot and a very good ending that leads to an expansion: F.E.A.R. Extraction Point, which I'm looking forward to play. Has anyone already played it? Is it worthwhile?
3 Sisters: Text based game, filled with a bunch of nice hentai pictures. I'm really enjoying this game!
Silent Storm: Good plot. Very good turn-based combat system, obviously influenced by Fallout. A very good game, overall. It has a few flaws, though, like the characters not being able to substantially improve some skills like Engineering and Medicine, making the classes Enginneer and Medic basically weak soldiers. A very interesting point is that you can destroy almost anything (anything, perhaps) in the scenery, like a house's wall, in order to hit your target.
Dwarf Fortress: I have been playing this for a few months already. So good that it does without graphics. Or "it does with its ASCII 'graphics'". In this strategy game you manage a dwarven fortress (duh!). You begin choosing your fortress' location, then your initial dwarves' skills and equipments. All dwarves have their own personalities, likings, and strange habits. This is one of the best games I have ever came across. If you do not know it,
take a look.
