Yes, but we were talking about 32-bit Windows the whole time. No 32-bit Windows will detect 4GB RAM (except some Windows Server which uses tricks) and that is because:

the Windows memory manager is limited to a 4 GB physical address space. Most of that address space is filled with RAM, but not all of it. Memory-mapped devices (such as your video card) will use some of that physical address space, as will the BIOS ROMs.

Is it just me or are EoF and the OP kind of ridiculous though. What you're saying is that you don't need to use the 64-bit system to play old games,
old games! WOOOOW! Can you imagine that? You don't need the latest technology to run something that is old. Wow. Just wow.
The point is if you run newer software you can only benefit from having a 64-bit OS, since compatibility is good and more and more apps are providing support for 64-bit.
