I actually enjoyed Doom 3 quite a bit more than Half-life 2, even though it's a flashlight-fest. I remember hitting the Hell level late on a Fri. night, was a bit intoxicated and my friends were on Teamspeak.. apparently I was quoting Event Horizon quite a bit.

AvP2 is a great game IMO, if you never played it. Sure the graphics are going to show their age, but playing as the human made me jump all the time. It's also interesting to play as the different species, each has their strengths and weaknesses.

Humans: Insane damage output from weaponry, gotta watch ammo, health is limited to medpacks.

Predators: IDDQD + IDKFA. OK so I guess they don't have a weakness really.

Alien: Ahhh... a stealth players challenge, esp. on hard. Few bullets and you are toast, but you can eat stuff to regain health. Wallwalking and the pounce are great for moving around.
