Actually, Halo had
3 enemy types. And
3 other enemy types. That's
6 enemy types.
The game world is divided into two exact groups on Halo/2. The first, is they hate the game for everything it has to offer.. The second, is they love the game for everything it has to offer. There's never a chance to cross the lines, because it's a decided-before-playing issue. People who hate the game and play it find out that yes, they hate it. Still, though, fortunatly there is a magical philosaphy of oppinions, so much flaming ensues over the internet.
Personally, I love both games.
The worst game I have ever played is, to say, Dues Ex: Invisible War. It was like playing Morrowind with guns while drunk with an orangutang hanging off your back while it masturbated. The controls were the clunkiest things I've ever dealt with (standard FPS controls, but placed in a terrible FPS). The dialogue came directly from KoToR, and the story was as exciting as margarin. I actually started shooting baskets on the basketball court in the beginning level while the entire base was exploding around me. I kept doing that till I made a shot, which took forever due to the games "Realistic Physics" that allows me to toss bodies 20 feet across a room.
Don't even let me get started on stealth. Combat is terrible, to. You don't need a gun, you can do everything using your melee weapons. Upgrading stuff is kinda cool (I put everything I found into this Poison Needle pistol that's initially terrible and made it better than a rocket launcher).
The only redeeming quality about the game was that I got it free with the Graphics Card I bought.
Another game I don't like, but only because people are blown away with it while I thought it was "okay"...Final Fantasy 7
If you attack me for that last comment, then re-evaluate your life, fanboy
