The biggest problem with these isn't their concepts, but their presentation. There's no video of either, and the Thomas the Tank one doesn't have any real screenshots or anything... it's just an idea. I could go on Kickstarter and be like "I have an idea for a platformer with these mechanics etc etc" but without showing any work, I'm just yet another person who potentially won't get any work done. I've done music for several indie games that didn't pan out, mostly because the project leader gets art, music, design done but then hits a wall with programming, and the entire thing falls apart. People want to see some proof that the game might actually get made. I pretty much require projects I'm going to work with to have a working game engine before I even consider starting working for them now.
The second one, "Lore," is a step in the right direction, but still comes across as a guy just playing around in Maya and Unity more than actually making a game. I think its biggest problem is also the rewards on the right. The English phrasing is kind of ambiguous and a lot of them are very long-winded. It looks like you never actually get the final game with any of them since they say "buy the game of steam are the website when its complete." The only screenshot that looks great is the Hades one, and it's just a mock-up by some guy on deviantArt. It would have been cool if that were representative of the final art style though.
