I'm always a bit baffled when people (both developers and players) spend so much effort reinventing the wheel with new systems that should allegedly solve all the "dumb limitations of these obsolete old RPGs", just to come up with solutions that more often than not end up having the same exact flaws, just in a slightly different configuration.
A textbook case of "solution in search of a problem", except the "solution" doesn't even work that well, most of the times.
DOS developers reinvented the wheel when created those attribute systems that DOS1 and DOS2 have. What I proposed is one of these "obsolete old RPGs" systems from games that were the best at their time.
