Ah, wow, this is harder for me to choose than I thought... Probably Minecraft, in my honest opinion. It was just so boring for me. The only enjoyment I got out of it was crashing it on somebody else's laptop as a joke 
Though, it's slightly ironic I consider this the worst game I've played, since I truly enjoy Terraria on occasions (Though, in my defense, it DOES have a lot more stuff in it, such as bosses for example)
