The general lack of love for Binding of Isaac: Rebirth around these parts continues to sadden me.
I haven't even played it yet (recently platinumed vanilla Isaac) but Rebirth might be my game of the year. I'm afraid of the amount of time I'll inevitably put into that thing...
The more I play it, the more I convince myself that it is the game of all the years.
If you liked vanilla enough to get all the achievements, I'm sure you're gonna love it. Dive in, balls deep!
