That is the crux of it. A small, but dedicated, core customer base. Keeping overhead and production costs low to offset the lower income.
We believe you don't need a massive studio or Patrick Stewart voice-overs to make a great game. Why do people still play a game as dated as Deus Ex? I believe it's because it hit all the right targets. It looks terrible by today's standards but I recently played it and loved it. A great story will stay with you much longer than a pretty image, IMO.
Deus Ex wasn't a small project. The type of games you are talking about making have significant development costs. Especially testing. And if you are planning on making your engine things get more resource intensive.
I am not saying it cannot be done, it has. Just that people who do this tend to live game-to-game and have limited options, if any, if a project is going sour.
What I meant was that Deus Ex is still being played today, even with its limitations. Not that it was a drop-in-the-hat to produce, and not that I want to make a graphically-challenged game mind you, just underlining the power of a great story with great execution.
We're aware of the potential complexity and associated costs, and as I said, early days yet. Without getting into too many details, I'm just trying to get a feel for the community's appetite for such a potential game (as outlined above initially) at this point.
Thanks for your ongoing thoughts though...appreciated.
