Halo 2's core gameplay IS deeper than Half-Life 2, though. Honestly, Doom 3's is deeper than Half-Life 2 as well. Honestly, I found the combat, weapon set, and enemies of HL2 to be quite disappointing. The game experience was amazing, but the combat itself certainly was not...
Here we go LOL now the fun really starts.
In terms of gunplay action - IMHO it's Halo2 > HL2 (by a hair) > Doom3.
Even though I don't own an Xbox, I agree as a shooter Halo2's mechanics beat out HL2 - in that there's a few critters in Halo2 that genuinely makes you work at killing them ( the annoying Jackals with the shields, the goddamn Jackal Snipers, etc..etc).
In terms of pure combat weapons the Battle Rifle in Halo2 feels way betterthan any weapon in HL2 (even though it's basically just the old magnum pistol recycled from Halo1).
The Gravity Gun is fun and all, and a bit unique in a sense. But at the end of the day it's just not that practical and doesn't deliver that satisfying sound of a gun cracking and the target dropping dead does.
In terms of overall as a game, I'd put Halo2 and HL2 on the same tier, with Doom3 a bit behind them.
If you enjoy a puzzle here and there as a break from shooting monsters in your FPS, build houses out of barrels and boxes, and play around with rag doll physics all day HL2 fits that bill rather well.
Despite all the Doom3 post-mortem hate, I did find the "zombie jumping out at you shooting gallery" gameplay to be fairly entertaining at the time.
was talking about VARIETY in level design and AI. VARIETY. Not who has the BEST ONE. VARIETY as in DIFFERENT AIs for DIFFERENT experiences in the SAME GAME. Do I have to explain the meaning of every word I use?
Heh I find it odd that anyone in questioning the variety in Halo2's level design and AI as it was as every bit as diverse as Half Life was.
IMHO Halo2 and HL2 are once again on the same level in terms of pure variety in both territories.
I didn't find Half Life 2's AI to be all that impressive over what I saw in Halo2. Least not better to the extent that I'd place one over the other.
