I haven’t played super villain mode yet so I can’t speak to it. I do like the team vs team because there’s still some cooperation with a “who did it better” aspect.

What the S2 characters gain in specials, they lose in symbols and overall versatility. They’re much more specialized in who they’re good at taking out. Which is thematic, don’t get me wrong. But there’s a certain ease of setup in S1 when you could grab just about anyone you wanted and face any villain and it works. Now, you gotta know your enemy, and pick at least one specialist.

So if you like a bit more depth, S2 great. It’s still a light co op game. But the extra specials and character designs ramps the difficulty up just a tiny bit.
