I ended up going through pretty much the whole thing without buying anything.
Just.... bleh. Nothing exciting right now.
I know the feel.
That said, I've recently lapsed into my Dwarf Fortress addiction again...
That's an easy one to fall into, yep. Been there, done that...
Currently though I'm addicted to Isaac and things that even remotely look like it. It's easy to fall into that one, too. Even if I had bought something during the sale I probably wouldn't be playing it yet, because Isaac.
