Look, I know some of you think Roblox sucks so this is only for the people who like Roblox but can't find any decent games.
Well, lets get cracking.

Zombie Apocalypse by Jewleycat:
Probably the best zombie game out at the moment. The point of the game is to survive 50 waves of the undead. Fun, but time consuming.

Heli wars:
This game is good if you want to just go and kill people for a while. However, the map is simple and people can spawnkill you.
Category: War
Rating: 8/10


Sword fighting tournament:
Awesome, just plain awesome. The only downfall is that the upgraded swords are too strong.
Category: War
Rating: 9/10


Survive the 90 disasters:
A classic game where you have to survive many disasters. Extra fun with adrenaline sauce.
