Love This Game!
I used to play the original (on PC, then Mac) back in the day so I was used to the format, goals etc. The old game was great for stock manipulations etc. which had more depth than the current game (I could make tons more money playing the stocks than I can now) but, apart from that, the new version still rocks. Graphics are great and gameplay is good. Runs under OS X Yosemite just fine. No problems.
