That's a bit funny, us pretty much beating the opposite games, lol.

Alright, in that case I'll be drawing from Heroman, Mazinkaiser SKL, and Gundam SEED.

I'm pretty sure Mazinkaiser SKL, Getter Robo, TTGL and Heroman can exist altogether on a version of planet Earth, if we just alter a bit of each stories plots and a few dates around a bit. However, I don't think Gundam SEED and the original Gundam can coexist with each other or the other series under normal circumstances.

Here's what I think we should do. We have our original, modern day Earth, which I'll dub "Super Robot Earth", with which exists TTGL, Getter Robo, Mazinkaiser SKL, and Heroman.

And then we have the universes and Earth's of both the original Gundam series, and Gundam SEED. 

We'll use the plot point from Z2 (don't know if you got that far) about "dimensional quakes". And we'll use the Dimensional Beast enemies too. I'd like you to pick a point in Gundam with which both the main characters, and their enemies get drawn to Super Robot Earth. I'll pick one too for SEED.

Up until that point, events in the Gundam and SEED universes will be scripted, until they get transported into the Super Robot Earth(and mostly on Super Robot Earth, but obviously only until the protagonists get their mech, and the enemy is revealed).

How's that sound, you get everything I just said?
