Jag är rädd för att det är på väg åt andra hållet... Det är först nu på senare tid flertalet spel inte har haft stöd för Mac <->PC. Visserligen har spelutbudet ökat till skillnad mot tidigare, men enbart det skälet får inte bli en ursäkt.
"Glenda: It always comes down to a technical or licensing issue. In some games, like Homeworld 2, the PC version uses DirectPlay, a Microsoft library for networking that has no Mac equivalent. To reverse engineer that (and not run into any legal issues) is an insurmountable problem, so we have to support on Mac network play. In other games there can be technical issues in the way the game's network code is written that cause problems. In C&C Generals, the game relied on bit-level floating point calculations being identical between players. So we'd have to guarantee every single calculation in the game produced an identical result to the the most minor decimal place when calculated on the PowerPC and the Pentium. There are enough small differences in how the compilers optimize floating point code to make those numbers not match, and so the game goes out of sync. Having a game that supports PC to Mac play but goes out of sync after 5 minutes would be worse than not having PC to Mac play at all.
On the licensing front, sometimes a game uses a proprietary game matching service to find other net players. An old example of this was the Microsoft Zone. Since that service was never implemented on the Mac, there was no way to have Internet play between PC & Macs in a Zone game. There are still a few services like that out there, and while we do everything we can to convince their owners to do Mac versions, we don't always succeed.
The good news is that we do have lots of fully compatible PC<>Mac games, like Call of Duty, Medal of Honor: Breakthrough, and Battlefield 1942. So for those people who really want to play against PC's, there are still lots of opportunities."
