Been playing Jurassic Park: Operation Genesis a bit lately. It's pretty much the only Jurassic Park game I've played (apart from Trespasser) that I would recommend to a fan of the franchise to play (I have yet to play TellTale's game).

I found a mod called the "Genesis Expansion Project" on ModdingGenesis.com that seems to open the game up a bit. The vanilla version is not the most complex tycoon-style game, but the mod helps a bit in terms of graphics, AI, and general gameplay. It at least seems a bit deeper than it did before. It's a lot of fun. I did have a tornado whip right down my main drag before I'd put in a shelter and kill a lot of people and a couple dinosaurs, but we managed to recover from that.
