I don't think it's unreasonable to want some game genres that are popular in the mainstream, but as I said in my last audeasy artical, i don't think the field of audio is being half as exploited as it should be, particularly in the matter of game ambience, and what is possible to hear and understand in the matter of game design.
I agree with Cx2 about the civ type game being a good idea. As to playing the mainstream version, ---- well personally i'd want some sort of way to overview my map and statistics in a game like that, rather than just working off the audio samples to react to events, ----- but then again, I'm a control freak, icemaster, is any of the game text actually accessible? or do you just work on the in game audio when events happen.
As to "Staying in a buble of rpgs 2d platformers etc" that's a trifle difficult as there aren't any yet. as I said, that's a trifle difficult sinse there aren't any as yet./ I only gave them as example sinse they would be genres of game we haven't got represented in audio, which probably should be, and which I personally can see a lot of potential and interest in.
there are several others. A decent real time football game, ---- and that's football as in Socker, for one (I had a design idea for this as well recently, even though i'm not a sports fan).
something in long term stratogy as Cx2 mentions, ---- though potentially I could see sound rts fulfilling part of this role if developement continues, partiularly in terms of much larger maps, better ai, more units, and events occurring betwene missions, ---- not to mention a decent story campeign mode (which is planned for next release I believe).
then, I'd love to see a propper! space combat game in 3D, similar to what flight commander was planned to be. A game where instead of moving from right to left, you actually have to fly your ship in 360 degrees like a plane, and have a varient of weapons and other systems to call on, ----- in fact, a complex flight game might be fun indeed (though sinse my best headphones have been on the blink and I haven't got to play 3D velosity yet, it's entirely possible we've already got one of these).
then, there's the matter of action/puzle games, the sorts of things where you move a character around a complex maze solving problems, or doing litle timing tasks, ---- similar to the bomberman or boulderdash games in the mainstream. I wasn't sure how these might turn out, but looking at aura, it's possible we'll get one soon.
then of course, there's the hole business of 2D, 2.5D, or 3D beat em ups in the one on one style, which covers a huuuuuuuuge range of games, fighting styles, interesting ideas about keyboard in put and moves, ----- not to mention the potential for great story and setting.
there are probably others people can come up with which I've missed. just to prove that rpg's aren't our only focus. Hmmmmm, maybe there's another artical for audeasy in this somewhere?
With our dreaming and singing, Ceaseless and sorrowless we! The glory about us clinging Of the glorious futures we see,
Our souls with high music ringing; O men! It must ever be
That we dwell in our dreaming and singing, A little apart from ye. (Arthur O'Shaughnessy 1873.)
