Games are so expensive to produce now, investors only want guaranteed returns, which means safe bets, which means sequels, DLC, episodic content or the same safe game rebadged. Havent you noticed the lack of innovation? The only new things coming out that arent cheap indies are mashed up genres.
Kickstarter is the only hope of avoiding this. It moves the emphasis away from having to compromise for funding (trading in a percentage of sales to give investors a 'cheap' version of the game) and in the same breath gauges interest. Small companies have a chance now.
Are you taking a risk? Sure, but given the people pitching its a negligible one. In return you will be getting a cheaper game, being involved in the development and more importantly, buying into a game that interests you. As for scams, it only raised $5k and it was the kickstarter community (through PSG) that busted them wide open. Id rather pay $15 for a game im actually interested and invested in than £39.99 on Modern Warfare XIXXII or Sims: The Workplace expansion set.
Ive done 4 so far, Ravaged, Shadowrun, Wasteland and Takedown. Currently thinking about a movie.
