I think they should've made cel-shading an option at least. Sometimes I'm in the mood for it, and sometimes I don't want it. There are a lot of qualms I have as far as graphics go between the PC and PS2/Xbox versions of the game. Most notably the characters. Elektra and Invisible Woman all have phuked up faces. I think Electra's base costume is the only one that doesn't have a screwy face. Invisible Woman has the same problem as Johnny, in that she looks like crap. However, the PS2/Xbox models look absolutely fine. It's sad when the PS2 model can measure up with the PC model, neh? So, I use the PS2 model for all Electra's outfits except for her base, and for all of Invisible Woman's outfits. Ms. Marvel's is also screwy. The first one is fine, and the binary is too ugly for me to use, so I assume that is fine. However, her original outfit has an annoying black splotch on her stomach in the PC version, and as Noel said, her face on the Ventura outfit is blocky. However, both PS2/Xbox versions are fine. There's also something I don't like about Wolverine's classic and astonishing outfit... I don't know what it is, but they don't quite look right. As teancum said, they are too shiny, even on the lower settings. I think Blade and Spiderman came out good though.
The PS3 and X360? I have no idea, as I haven't seen any of those in action, minus the screen shots for the DLC. I only noticed those characters though, because that's who I use the most.
I think the initial problem is that they just rushed this crap out, being that the PC version, from what I hear, is just a port from the console versions, not the other way around. However, in initial testing, this Chocolate egg is REALLY obvious. It's not like I sat down with a magnefying glass to look at the game to find out what's wrong. I noticed the screw ups the first time I played, which made me really disappointed. I hope they didn't do the same for the DLC. And I hope they realize that if they actually ported it to the PC game themselves, they stand to gain at least some profit. Because if they don't, we will, and they will get absolutely no profit from it, not to mention then a lot of people (more than if they would release it for PC anyway) will get it for free. I hope they pay more attention in the future, and I hope they continue the franchise.
