My brothers kids are that wonderful brand of new age children with the attention span of mayonnaise and who spend their entire lives attached to digital devices or they turn into a wailing pile of tears and brain AIDS. They love Minecraft. Correlation does not imply causation
I bought Terraria and played it for about 2 hours. I built a house, had a bunch of numpties move in and enjoyed the strangely creepy music. Then I realized, there is really no objective in this game other than to Derp around looking for shinies while you get ass-raped by magic eyeballs in the dark while you're deep under-ground. Sounds like that night I spent in LeRoys Basement when he slipped me roofies and I woke up with a sore asshole. Bad feelz.
They said "It's more fun to DERP with friends" so I did, and I found it mildly less AIDS-infested, but it was still an e peen -2.
Minecraft... well, I didn't even bother with minecraft. God bless my nephews, but if they DERP around on it, then it's gotta be E peen -5.
