King's Bounty: The Legend is absolutely worth it if you don't already have it. It's a fantastic RPG.
Of the other games in there, I liked Fantasy Wars (turn-based strategy combat game, predecessor to Elven Legacy), the two Real Warfare games (not great, but serviceable Total War-type games), and Men of War: Vietnam (probably the worst of the MoW series, but I'm a sucker for those types of games, not that I'm any good at them). Death to Spies: Moment of Truth I haven't played yet, but I've heard good things about it, assuming you like your stealth games to be quite difficult; I played its prequel, and I couldn't make it past the 2nd mission, although I still came away with a favorable opinion of it. Reign: Conflict of Nations is a strategy game that I really, really wanted to like, but it's mediocre... might be worth playing, but other games (i.e. Knights of Honor) do the exact thing much better.
Haven't played the two racing games or Star Wolves 2 (which is on my wishlist, although I've heard it's a decent game buried under a buggy mess).
hmm, well that sounds like it's worth buying. I have very little experience with RPG and strategy games though, are these hard to get into?
