Yes! Thanks for replying so quickly Ninjabee.
That would be amazing. With how much game variety Steam has today, especially time management sims and service industry sims, it would be great to have OKX there. It's a very iconic piece of the X360 era for me.
Wikipedia says that X has "enhanced graphics", "More than twice as many levels on the Xbox 360 release, including extra campaigns and scenarios" (this probably means the War Path, extra levels, and the DLC challenges and Love Path?), and "a leaderboard and time challenges".
Thanks again!
