Actually you can just make a 32 bit version so that all 32 and 64 bit computers can run the game. The difference between a 32 bit and 64 bit executable is that the 32 bit could only use up to 2GB virtual memory, while 64 bit can use up to 4GB. Most games are still compiled as 32 bit, so it is fine to make a 32 bit executable unless your game requires more than 2GB of virtual memory.
