Quoting Amnesiac (view post)
It would be so incredible if a third game came out, though. Those screens really do look great.
I have ot jump on the bandwagon and say "HL2" is one of the best games ever.
And not to keep harping on it, but "Batman: Arkham Asylum" is up there too. Pay attention to pacing in games? This one, like "Shadow Complex" and other "Metroid"-style action/adventure games, has the player constantly picking up new, useful items that unlock areas of the map which were previously unreachable. Every few minutes you're accomplishing something of great value, and every 15-20 minutes you're unlocking something new - a new gadget, a new place you can go, a new variation on the detective visor.
It's just an impeccably crafted game.
Free-flow combat has to be one of the greatest innovations in video game hand-to-hand combat ever.
