Having a 3DS, I will probably buy it. Im obviously not expecting a portable RCT3, but I think that the game looks good for entertainment value, rather than the enthusiast appeal. I do have to agree with the above that a Patch of some sort for modern computers would show a bit more commitment to their fanbase by Atari, but they just seem to forget us and move on the more casual market, but being a business they have to appeal to a wider market than the commited fans.
