I've been using the software so long it's crazy -- I started with Don Miguel's patch of RM2K, and I've made a few games with RM2K3; it's my preferred revision, limited though it may be, of the software thus far (though Super Dante is a close runner up).

Interestingly enough, I never use the software to make actual RPGs and always attempt to create games of other genres instead, such as adventure games, board games, and maze-runners.
