I figure if anyone else is into this kind of stuff, go ahead and use this topic to post your creations. I'd be really interested to see what others have created in games, whether it's your own original character or a version of a pre-existing one.
I was just messing around in Armored Core V, and spent at least an hour this morning piecing together, picking the right colors, and creating decals for an AC version of one of my personal favorite videogame robots: Robbit from Jumping Flash.
Had to give it reverse-jointed legs to keep its jumping ability high.
Couple more pics in the spoiler tag:
Oddly proud of this one, aesthetically, even though the actual AC setup isn't all that sound.
The "Universal City Hall" decal (first pic in spoilers) is almost identical to the one in Jumping Flash, and the Superman-esque shape of the "R" decal was hard to make, since it doesn't actually exist in the game; had to piece it together with other shapes. Also note the yellow-frosted tips on its "ears"; not a hard effect to do, I just like the detail.
So if you've got any creations of your own you'd like to show, post 'em here. I always like seeing this stuff, whether it's an original character or an homage like this one.
And don't worry about picture quality; if you can't take screenshots, just snap it with your phone or something. It's all good.
