Warning: TL;DR ahead!
I think a lot of people (generally directed) needs to understand that what we knew as 'adventure klick and play' games, is dead. That era is over
Personally I would love to have plenty of games in 2D, just like the good ol' days, but it's not gonna happen. Too bad, but alas, get over it.
However, I can also understand why people are a bit "afraid", look what just happened to the Larry series, since the market for the klick 'n play is (nearly) gone, they turned it into a... erh, yeah, whatever they turned it into.
At the other hand, there are plenty of interesting things happening right now. Dreamfall
(sequel to 'The Longest Journey') looks promising, and 'tho they've stated it won't be a pure adventure game, they're trying to make innovative solutions for the genre, and I think it's needed. Things can only get rehashed so long, before getting boring.
Thats why I think the whole 'episode' thing would work so much better. That way, you'd get more incorporated into the game. Troubleshooting will be very good (what didn't work in one episode, can be heavily worked at on the next, etc), the history won't feel lacking at times (some games suffer from this, you get to the point were you're thinking, ach, no... not this part), and so on and so forth.
I think this is great, and a intresting time for gamers. I believe people will grow more and more weary of all these Half-life-clone-FPS that seems to flood the marked. Eventually people will start demanding something else, and maybe we're seeing the first few steps.
