I only barely found out about UC when I stumbled across the trailer in RE4 a week ago.
It looks great and I've been hoping for a remake of 2 and 3 since 1 was redone for GC. However, I don't like that it looks like one of the survivor games.
Also is 2 even covered in this? So far I've only noticed stuff out of 0, 1, and 3. 2 was the first RE I ever played and still my favorite, and I'll be disappointed if they don't include it.
