Doesn't really have any competition, but they still try their best to keep at the top of the game. Great modules, great community, runs very well on a varied array of systems. Could use a graphical update in some areas, ground textures some places are quite poor, clouds are painfully outdated, and desperately needs a dynamic campaign engine. With that said, it's still an awesome sim/game that I've sunk thousand of hours into. Not an arcade game and pretty much it will find ways to make you go crazy... RETURN PRE CONTACT.
