Makes DOA 2 the best in the series, and DOA one is slightly improved.
DOA - your basic fighter with limited stages. I love this game, but it is hard to go back to after playing 2, 3, and 2 Ultimate.
DOA2 - this new revised version is much better than the original 2, and they added in an improved 3 engine, making a superior fighter than 3, and thus the best DOA yet.
Graphics:
DOA - meh
DOA2 - hell yeah!
Sound:
1 has alright sound, 2 has really good sound.
Replay:
Very high, for both. With each having online play, you'll keep coming back.
Overall:
A must own collection/revision for DOA fans. And for those who missed out on 1 and 2, get this now. 1 is something fun to play to see how much DOA is evolved, and DOA2 Ultimate is the best DOA yet. Buy!!
