Some want to be able to develop games using the software mode, which has far greater compatibility for older systems and for those who want to make a simple game. My 2D game would otherwise fit into this, but I need support for 24-bit color and A5 doesn't have that, so it's not an option. 24-bit color was only implemented into the 6.31 update. 16-bit color looks very bad, considering all those gradients I've got and 32-bit color would otherwise just end up wasting both disk space and memory and not worth it. I just mainly posted the feature comparison chart so users would know what each edition from A5 supports. I got it off the internet archive.
