I'm not here to argue as I haven't played either game (I only played warhead), but if the game isn't better than the first one, it's setting itself up to be called bad. By creating a sequel, they are expected to make it everything that the first game was and even more. If it isn't even as good as the first well then...
Perhaps their "even more" was just expanding it to consoles. They abandon their core user base (in a sense), but I bet they make way more on it than they did on the first one, just because of the wider audience.
IMO Crysis 2
IS the better game to me. People can have whatever opinion they want, but I'm having an absolute blast in the sequel. There's so many Crysis 2 threads that I'm losing track of where I post what, but here's what I said in one of the other ones:
I'm having no problems with stealth. If you think it's too run and gun, then that's how you're playing it. I just got done with the first area that had nothing but aliens in it, and I was actually surprised at how I was playing the game similar to how I'd play old school Splinter Cell games. I'd isolate enemies and get a stealth kill, then (while still cloaked) jump over the kiosks to stealth kill the one who's shooting where I WAS and not where I AM
IMO this one is much more balanced in how you can approach things vs. the first. In the first you HAD to go stealth or you'd get demolished. In this one you can go stealth, explosives, guns blazing, avoid entirely... all sorts of ways. I think either people had a ton of mods on, or just simply remember it fondly because it was good for the time.
I hadn't played the first Crysis till last week, and I thought it actually didn't look very good. My first thought was "this is what people have been so happy over? meh..." But with a texture pack it looks fantastic. Exactly what this one needs. The big thing though was I just wasn't having fun with Crysis. It was wide open sure, but anytime I tried to do something interesting I'd get killed immediately. Maybe our styles are just conducive to enjoying each game differently, but I truly believe that this one from a gameplay perspective surpasses the first. And this is coming from somebody who played them right next to each other.
