Ynlraey, I'm assuming the background is ripped from this Super Robot Wars, yes? Are the faceset/sprite original, or also rips? I've never played, so I wouldn't know. Anyway, I'd steer clear of straight-up, in-your-face references such as those. Much more subtle references like quoting lines and such would be a lot better, imo. When they're as blatant as that, it makes players who haven't played the referenced game feel left out of the loop, and doesn't give those who have played the ref material the smile that recognizing where a certain line or item came from does.
