Both. Hoping to finish at least one full playthrough of RE2 before KH3.
But there's so much darkness in kingdom hearts /sThere was a thread on this topic a couple months back, but as both release in less than two weeks I don't think it's bad to gauge this.
Both are really different games, apples and oranges here, so really it depends what type of game you prefer. Of course though as a horror enthusiast who specializes in PC gaming, Resident Evil 2 is the one that has won me over.
