its a good game, not just for the sandbox, there are a variety of game modes to choose from. it is worth paying the $10.
the ttt (trouble in terrorist town) mode is quite fun you have to try to find the traitors or if you are a traitor kill the innos. (innocents)
if you like fps games are death match modes but some require you to earn money and it can take alot of time.
i find the sandbox annoying and a big let down
people go in the game expecting to be able to make houses and cars with out having to spend hours of place materials but it can take too much time to make one thing.
singleplayer review: the single player is where the game really goes downhill its straight up boring especially if you hate sandbox the most fun thing you can do is probably spawn and shoot npc's and balloons very disappointing this is the big reason why my rating is not higher.
