Halo for the PC is quite good fun. The A.I. is superb - the first time an alien rolls away from your grenade, you'll be so suprised it'll have shot you full of holes by the time you recover, and the first time you look up into the sky and see the curve of the Halo stretching away into space is one of those "wow" gaming moments that happens all too rarely. If you like semi-hard SF settings then you'll enjoy the story-line too ( its not often you get a plot where humankind is gettings its butt kicked all round the galaxy... )Edit: It also seems to be very well regarded as a multi-player experience, but thats no something I've tried myself.But... theres a bit too much running down very similar looking corridors, and halfway through the game they introduce something that completely undoes all the previous wonderful A.I. programming.It also requires a fairly nice PC to enjoy the best graphics.KOTR is also very good fun. It has some weaknesses - again, a bit too much running down corridors, a slow start, some poorly chosen voice acting, and late on in the game Jedi are so powerful they pretty much make the supporting characters redundant.On the other hand, the production values are generally very high, the NPCs are all well-developed characters ( the war veteran who tells endless stories of battles hes fought in is one of my favourites ), you have more freedom to develop your character than most other games of its type, the story is very engaging, and - this is important - it has atmosphere coming out its ears. There is nothing - nothing - like getting your first lightsaber and hearing that "vmmm-WHRUM-vmmm" noise as it bursts into life.It makes up for an awful lot of corridors.
