There's just something about the established classics that might as well be cursed when it comes to projects out of nowhere from random teams.
I'll tell you why: programming has changed, random teams are just a reflection of nowadays developers' stock.
In 1981, to be a game programmer, you had to be a genius. Okay, maybe that's exagerating, but most of the competent programmers capable of doing a game, were rather intelligent people, self-taught, that used horribly impaired tools compared to nowadays. There was no "official" way to program a game, and most hardware wasn't actually designed for it; optimization, tweaking, debugging, everything was hard, and undocumented. Not to mention, it was a very small market, and with small profits compared to what the same guy could earn, if he was programming COBOL shit for a bank, which would also be more "respectable". Being a videogame programmer in the 80s didn't really sound cool... it was a kiddies' thing, for many people. So if they were making games, it was probably because they had a
passion for it. They were talented(ish) dreamers.
Nowadays, programming is easier than ever. At least to a superficial level, the learning curve to build and even publish a simple application, is extremely gentler than it was before. Anyone that is not seriously mentally-impaired can follow a tutorial and make a calculator application. Sure there's some extraordinary programmers around, but there's also the horde of goons that just learned how to use the shiny tools, drag and drop widgets, and managed not to get too drunk before university tests, so they got a degree that makes them "qualified". For them, videogames is a "career" with a lot of "earning potential". That explains AAA games with memory leaks or absurd requisites... because in the end, the shiny tools have small cracks, and there's always some need to go low level, which these guys simply can't handle.
Now compare a team of old-time developers, to the ones I just described, and tell me if it is surprising that the final outcome is not the same.
Not even considering marketing pressure and other factors, which obviously don't help.
