Given the recent massive kickstarter success for Double fine's adventure game kickstarter which made over $1million in a single day there are a couple of others that have appeared and look very interesting.
Firstly the creator of Wasteland the original post apocalyptic RPG game has launched a kickstarter of his own to try and financeWasteland 2. Brian Fargo is in many ways the father of Fallout (he also headed Interplay when Fallout 1 and 2 were developed) so hopefully if this comes of it will be a game to watch.
The other one that caught my eye was a suggestion from Obsidian (who's core staff essentially made such greats as Fallout and Planescape torment) that they would be interested in a kickstater for an 'old school isometric RPG'. Planescape torment 2 anyone ?
