The worst thing I find, mostly with games on Kickstarter is that they set an initial goal £100,000 for example and then they hit it, within two days. So then they set these stretch goals and go "well at £200,000 we will add air combat to this game", "wow £300,000 awesome, now we will add naval...you guys don't mind us adding an extra 2 months to development right?" Wrong, don't estimate 8 months then when you get more push it further back.
Some of these games (Elite for example) is set to ship March 2014, that's over a year away and you're expecting me to pop £40 out now for a game I may or may not see in 15 months, what is my incentive here other than I may get a £2 discount on a game in the future.
