mode 7 has some problems showing tiles that are supposed to have depth on the z-axis.  Take this example:

look at that building in the lower left.  It looks totally flat because it pixelled from a top down/pokemon style angle, but its being stretched out into perspective and the screen is rotated.
Take a look at this approach:

all the things with z-axis depth are drawn over the screen as sprites (the tree, char, bridge rails), which is much more effective.

This is the sort of think I associate with mode7 (lack of z-axis, made up for by drawing sprites over the screen without perspective).
Something like doom where it actually is 3d with a z-axis feels more like normal 3d just with lower res graphics and using sprites instead of models.   Doom can also scale sprites that are farther away.  I dont think mode 7 could do that.  Racing games on the snes like f-zero and mario kart used seperate smaller sprites as cars got farther away rather than just scaling 1 sprite. Is something like Doom what youre going for?  For that I think doing tiles from top down perspective works fine since youre probably just drawing floors at that point, and you can actually add walls for things on the z-axis.

IF you could clarify what type of thing you want to do with the perspective it would help though.

Wolfenstein 3D is super simplistic in that it only supports a static wall height. It's basically a 2D map mapped to 3D perspective through raycasting.

I don't think any version of DOOM uses Mode 7, not even the SNES port (which instead uses a Super FX chip to bypass hardware restrictions.) DOOM uses a voxel engine to draw 3D spaces.

You're probably just best off drawing pixel art and plugging it into a voxel or polygonal engine, like this: http://www.youtube.com/watch?v=uAXA0zDIwJ0#t=47s (a DOOM mod). Just... for the love of all that is good have some sense to use different tiles for walls and floors.

Honestly, I haven't done anything. I'm most likely going to have to spend a lot of time just honing what little skill I have to flesh out the graphical aspect of the game. It's mainly just a vision I have..

An old-school adventure/platformer homage to games like Earth Bound and Legend Of Zelda: Oracle Of Seasons.. I'd like to take major elements of both games and push them in a different direction..

I think that going for this particular perspective is sort of unnecessary, especially since I don't know a lick of coding.. lol

If anything, I'll just work on the tiles/sprites based off of the type of games that I've mentioned, I really just wanted to have background scenery like skylines, castles in the distance, etc.. Which is sort of hard to have from that sort of perspective, but I guess Earth Bound did have "ceiling" tiles..

Well, I'll check it out for the time being. But I'd be more interested in actually finding a programmer/coder to actually create the game from scratch. Y'know, once I have a percentage of the game finished graphically.

I'll look into RPGM, just so that I possibly have a real-time canvas for whatever I might end up with.
