Why would you add ROBLOX? Guuh, that community is full of 9 year-olds trying to act like they are 15. I do admit though, I used to play before I found out about Minecraft. I also must admit that I didn't think Minecraft was very good looking until around 5 months ago. I heard about "MC" (Because you would get banned (Wtf. My point exactly) if you said Minecraft) and wondered what it was, finally I searched it up, saw you had to pay, and didn't buy it. Then, I watched the Yogscast play this game, and instantly wanted to buy it. WOW. Thats my life story. >.<
Minecraft is good, but not the best. More of a time killer, when I'm bored of other games.
Runescape is just grinding, so it's extremely boring.
Although I don't like the series, CoD2 > BO.
Didn't really like Terraria; Minecraft is much more appealing to me. Got bored after half an hour and never played it again.
Don't like any of the Mario games.
Portal is too short.
Portal 2 is truly amazing, but again, it's too short. Might change my mind once I get a co-op partner, though.
