does a sequel always have to massively innovate?
what's wrong with a sequel just giving you more of the same that you clearly enjoyed?
classic games are still heralded compared to modern titles, and imo it's innovation that has ruined alot of classic franchises, such as resident evil and sonic the hedgehog.
compare sonic 2 with sonic 1, apart from having 2 players, it's the same game just refined. different levels is what people wanted it for, having played all of sonic 1s levels to death. now look at sonic 3, which is a great game, but they tried to add too much to the formula, from game mechanics to shiny rendered looking graphics, and overcomplicated it which is why sonic 2 and not 3 is still seen as the best in every poll ever.
resident evil 1, 2 and 3. they're still great games today, resident evil 6 was boring after playing just the demo. 'innovation' ruined it, turned it into a shooter that isn't scary, rather than a puzzle game with a b-movie scary feel where dodging zombies (like in proper zombie films) was the order of the day rather than gunning them down.
dead space. people moaned at the lack of innovation in dead space 2 compared to 1, and it certainly looks like they're ruining 3 by 'innovating' it. me? i just want dead space 1 with a new ship to explore, perhaps some new scarier enemies (not humans, to have gun battles with).
final fantasy. they perfected the combat in 7. everyone said so. it's still seen as the best in the series. yet they insist on 'innovating' the combat system each time still, receiving lower and lower review scores each time. just make 7 again with a bigger world / nicer graphics already!!
honestly, i don't get this 'innovation' in gaming being so important. IMO, a game that has sequels should just be giving us more of what we loved about the original, just make sure it's done at least as well. if you have some 'innovative' ideas to add to the game, you should take those ideas and make a new game with them, rather than bolting them onto an existing game in the name of innovation.
look at grand theft auto games, they've got it right. the reason everyone still loves grand theft auto games, is because they're the same game it was back on pc as grand theft auto 1, only with shinier graphics and refined gameplay.
so devs, ignore these cries for innovation. if a game sells well and has many fans, those fans will happily just play more levels of that game as long as they're made as well. mario games, call of duty games, grand theft auto games and fifa games are all good examples to follow! if you want to innovate, don't ruin your good games, just make new games / franchises!
