Yeah, more or less what Cameleon said. When there's a demand for such a classic return then I think Kickstarter is a viable way to go about it, especially when it's just "the original creators" and not a complete production company. Adventure gaming suddenly became newsworthy again, shortly after Wasteland 2 was announced, and since then several other big names have stepped up to capitalize on it. I have no problem with this, it's a new market and they're experimenting with it.
That being said, has anyone been clambering for a new Ecco game? Seriously? Ecco is not relevant at all, I am very confident that this kickstarter won't succeed in doing anything except disappointing those few that were genuinely hoping for a new game, and killing any chance of it happening in the future.
