SimTower in Intel Tiger

I really enjoy the game SimTower, although I haven't been able to play since I switched to Linux a couple years ago, and added this Mac about a year ago. I recently started looking around for ways to run it, and found myself in an assortment of how-to's for Sheepshaver. Sheepshaver sounds a bit complicated for one game, although if someone with firsthand experience could tell me if that's an accurate assumption, I'd appreciate it.

So on either my Intel Tiger or my x86 Linux box I'd like to run SimTower. Any suggested methods or tips would be appreciated as I continue my search. I would love a simple game emulator, but I haven't found a solution yet.

Thanks,
Chris
