Yeah but those things don't make a game an all time classic. I'm mean the game was a good shooter, but imo it doesn't deserve to be in the top 10 of best videogames.
So what makes FFXII an all-time classic if Halo isn't?
The recharging health scheme has been copied in nearly every console shooter since as the genre has moved away from the 'health counter and health pack' meme, and it gives game designers a way to allow enemies to be effective in combat without making things frustrating for the player by punishing you for making minor mistakes or getting hit by a 'lucky' or 'cheap' round of fire. Gears of War, Resistance, Riddick, Rainbow Six Vegas, Call of Duty 3/4, Crackdown...they all use this system now.
When someone speaks of "Legendary AI" they're speaking of the AI on the Legendary difficulty level, which I imagine few gamers here have a) tried or b) beaten solo. It's that hard.
The two weapon system is again something that's been copied by many console (and some PC) shooters since. It adds a layer of strategy knowing that you can't walk into a battle with an entire arsenal at your disposal, forcing you to plan ahead on the kind of enemy you're facing and think on your feet by scavenging for new weapons. For example, walking into a large firefight with the two of the stronger short-range weapons (Shotgun and Plasma Sword) is actually a bad idea because you'll be killed before you can get close enough to use either, while trying to do some close-quarters battle with the Rocket Launcher and the Beam Rifle will end up with you blowing yourself up or getting shot in the face while someone dodges your slow bullets.
Blood Gulch is one of the most well-known multiplayer maps in console gaming, it's up there with Temple and Facility from GE. Halo basically brought LAN console gaming to the mainstream.
The preferred control scheme doesn't automatically make every other area of a game good. People don't walk around arguing that Tron 2.0 > Halo 2, or that Doom 3 > Gears of War,
just because of the mouse and keyboard, because that's just crazy talk. The fact is, people always talk about all of the FPS that are "so much better" than Halo, but if you sat down an unbiased person in front of both games, 9x out of 10 they pick Halo. 8 million in sales doesn't lie.
