For me i would have to say Runescape. Everything in Runescape is only allowed for those who pay monthly and those who doesn't will feel extremely limited to the features of the game. If you're going to pay for a game, there's a lot more better games out there to get addicted to.
I'd have to agree with supermape123. I've played many, but I can't recall them. I didn't put them in my memory (wonder why?). Sorry. If I remember, I'll post it here! And, I'll add a link (don't know why you'd want it). :P
uuuuuuuuuuuuuuuh. it depends. online game means a couple things. as far as downloaded games played i would say WOW. if u mean browser games, i dont remember the name, believe me, it was bad
I gotta agree with supermape but one that stands out is definitely adventure quest. I absolutely hate it. I tried it once and now it spams my email telling me to come back and play and I swear they send me at least 3 per week.
The Game is the worst game for me. I can never win it.
That's because you don't cheat.
I've played a ****load of bad online games, the problem is that I don't bother to remember their names when I do. Runescape is one, but another game called Tibia is actually even worse.
