Entertaining for you != everybody else. I used to play Halo CE alot - why? My friends played it online so i played with them. It’s fun to play with someone, but when it comes down to it, there are more interesting games.
One of the things that puts me off from halo is that everything feels generic, the aliens feel like cartoons, and the Marines and their weaps are rip offs of the Colonial Marines from aliens. The only enemies i found to be interesting were the flood somewhat, but even they were overglorified zombies when it comes down to it.
Halo Custom Edition, now, THAT I must say i actually had fun with. It was cool to see all the new and unique maps being made for it, each like its own mod with new weapons and such. Sure a lot of them sucked, but there were a pretty good few.
Other then that, though, the mp feels like a slow Quake (partially due to taking so many bullets to kill, aside from large weaps and snipers) except with vehicles. The only thing i was really impressed with in CE was It’s warthog driving physics, which, IMO, are some of the best I’ve ever seen in a game - it was so fluid. The other Halo games, and other games in general, it just isn’t as fun to drive.
It was exaggerated, but still, great fun
