I almost bought stuff yesterday but decided to wait. Today I got Xcom for $12 with 2 DLC. I picked up FTL for cheap too, but opted out of Terraria and the Binding of Isaac.
Terraria looks fun but it also looks like a huge time sink ala Minecraft. One MC addiction was enough thanks. I realized Binding of Isaac just wasn't my thing after watching a Youtube play through. It looked fun, it just wasn't really what I thought it was.
