Right now I'm alternating between Pharaoh and Elemental:war of magic
Pharaoh because it's one of my fav games ever and only recently I found a nocd patch (misplaced the cd, but game is installed) whereas elemental i bought hearing stardock really fixed it up following a disastrous release, and indeed they have, Elemental's story is now the same tragic story as games such as Vampire Bloodlines: a promising and ambitious game that was critically demolished on release due to really bad bugs but devs stuck in and patched their game to the point it ruined the company, succeeding in making an awesome game in the end at a heavy price.
