I *love* isometric perspective in everything but I'll be honest, I haven't played many games using it simply because they tend to be of genres that I hate (tactical RPGs, RTS, etc). I only played a few through emulation over the last decade that were more action-oriented.
Equinox has fascinated me ever since I read about it in an old issue of the Nintendo Power magazine and especially the overworld. Sadly, many early SNES emulators didn't render the overworld correctly and I only recently switched to a more accurate one (BizHawk) that allowed me to map it properly. I've been putting off making a thread about it for a few weeks because I was hoping to be further along on the dungeon maps but if I keep waiting, I know I'll just put it aside and eventually, someone else will end up mapping it instead. I guess I should get on that soon, right?
As for Landstalker, I'm sure I would have loved that game back in the days but I have to admit, isometric games are more fascinating for me when I'm actually exploring and discovering them. Once they've all been mapped, the mystery is gone and I tend to quickly lose interest. Heck, I've recently realized that I regularly buy games mainly because I'm curious to see how the game world fits together and to see awesome-looking levels and once I've seen everything, I don't even bother finishing them!
