I kinda enjoy these games, although there's not much action in them, just like the flightsimulator games. The only one i have so far, is
Railroadtycoon, which is quite an amusing game, very hard, but amusing nonetheless. The real deal however is
this baby from Microsoft. I don't have this one yet, but it's on my list of "things to get". So i can't tell you much about it, but i expect it to be a fun game, with great scenery.
