So, if it's getting better then they do care to make good games? (and though I may sound like i'm mocking or something I'm not)
Because what you're saying is confusing me.
They get better overall, but certain things are not as good as they were in previous installments.
Take a game series like Fable. As much as many people prefer the first one and complain about latter versions, in many ways, the newer ones did improve on the title. The graphics got better, the world got larger, co-op, local and online, was added, there were many more customization options. . . but for all the things they added, they also took away things that should have been kept in.
Omega is concerned about the ES devs throwing the baby out with the bathwater, as the old saying goes. Yes, each ES game has, overall, improved upon its predecessor. But the improvement is because, when the list of pros vs. cons is held up, the pros outway the cons. It isn't because the newer title is without flaws, nor because there were not some things which the prior game did better.
Skyrim could have better graphics, better stories and quests, better appearance customization and more hidden items than Oblivion.. . but have a worse spell system, the same horrible omniscient guards etc. and therefore IN THOSE AREAS, it would be no better than or even notably worse than Oblivion. On the whole a better game, but with certain things that were more badly broken for having been tinkered with, rather than fixed. And for some people those tinkerings and their results could prove to be, if not game breakers, than at least serious impediments to their enjoyment of the game.
