nah... a house with 2000 polys is okay. its freaking 2007 people... heck, even ps2 games feature more polies than your replies... 2000 polys, + normal and specular mapping... thats a fine job...

my game has 45 000 polys visibla yat any time, plus toon shader plus level geometry and actions. i never drop below 35 frames per second, and i have an old system (AMD1.6ghz, 512ram, geforce5200fx)...

heck, polys even render faster than sprites. the skins is what eats up the frames (depends on your system, but mostly, this is correct)...

so you can add a few mored etails if you want...
