Half-Life 2 (waited for this for half of my life)
Deus Ex 2 (yeeeeeeehaw! Could I please have the implanted nightgoggles?)

It's time for sneakers and "think"ers. Well, I might give Doom 3 a try - but as soon as it turns out to be "Doom" just with high-end-graphics, you can count me out! So, JC, do your best & hire a couple of story- and suspense-experts (whoever and whatever that might be).
BTW: System Shock 3 would be a nice one, wouldn't it?
...we yet realize that America's leadership and prestige depend, not merely upon our unmatched material progress, riches and military strength, but on how we use our power in the interests of world peace and human betterment.
