Infinity Engine Viewport with those sidebars, prerendered 2d maps with touched up artwork or bust. I refuse to call everything besides that Baldurs Gate.
Give me a game that uses the AD&D 2nd Edition IE, beautiful 2D art, good sound design, and has serviceable writing that captures the interest of the player through good world building, and we'll have a GotY and top 20 RPG on our hands.
It's a shame that Bioware/Black Isle didn't milk the ever loving shit of IE. The decline would have eventually seeped in, but perhaps we would have gotten 2-3 more classic RPGs out of it before that was the case. IE had so much potential man, just give us new enemies, encounters, characters, settings, and items. The rubric was there!
