I have been minecrafting hard lately! Originally an Xbox user, just recently broke down and got the PC version 1.7.5 and I love it. I hate how many creepers there are in the PC version! It seems like an insane amount compared to Xbox... I mean like eight creepers around my house and they never go away!
I think it's just bad luck. I had to build a stone wall around my house in the xbox version because every time it was night there would be about 5 or 6 creepers spawning around/in my house despite the area being lit.
I actually found out there was a zombie spawner in my basement and it was spawning zombies in my basement and they climbed the stairs up and broke down the doors. Scared the crap out of me.
