Level 99 Demi-fiend
The problem is that nowadays, games are too much of a high risk high reward scenario. If you compare the amount of releases back then and now and the cost of making them, you'll notice less games are being released but the cost remains largely the same. And with games being "more mainstream" and multiplatform distribution, making something bug free is almost impossible. You have to take into account the console, or god forbid hardware specs of different PCs, to make sure they run.Simple question, do you think a lot of games especially sequels now suck or do you think its just nostalgia?
#1 Updates and patches.
Therefore, it's a lot more beneficial in the long run to do some QA and if there are some bugs, fix it when you can. You can't really afford to spend so much resources on making sure something is bug free and then expect to break even. Not a lot of games can do this.
As for the answer about sequels, is that really a bad thing? Dragon Quest games are still pretty good no matter what. Final Fantasy still has good games even at their worst as each their own has charm. Dept. Heaven episodes expand on the stories with "sequels" or "continuations" that just can't fit a single game. I don't see anything bad with sequels, at all.
And while we're at it, I don't see anything wrong with recreating or rebooting a franchise as well. I don't expect people to grow from an era of amazing 3D graphics to play Tomb Raider 1 which, in all honesty, has very bad controls. If we think "Sequels" or "Reboots" are bad, then we wouldn't have gotten amazing games such as Resident Evil Remake available outside of just gamecube. Which deserved much better.
I would disagree on Mods being a bad thing. It has been a thing since early games such as DOOM and will always be. Why not make it more accessible? Mods allows users to express themselves and learn creatively on a medium they love. Why would you stop them? A lot of people started with Mods and now work for the industry. The same way as people started with drawing fan stories before they become professionals.#3 DLCs and Mods
DLCs are a hit or miss for me. I don't think they are necessarily bad. Case in point, I love the Don't Starve games but I would be lying if I said I hated the DLCs they are releasing. They're great additions to the games and I would love them to keep expanding it. If it also helps DST to remain online for survival multiplayer and no subscription needed, I will happily support them.
