PaterAlf: And the problem is they don't have to wait for long: There are several indie games that appear in bundles or promos only one month after their initial release.
Remember Botanicula? The game that was featured in a humble bundle the day it was released on GOG?
PaterAlf: I really think developers are shovelling their own grave this way. In a long run it might also not be a good idea to give away more than one key (Desura, Steam, GOG, DRM-free download) with a purchase. Sure, there are lots of people that don't abuse it and who are just happy that they can add the game to each of their libraries. But there are even more that use the possibility to multiply the license (they paid just a few cents for) and give away or sell the keys they don't need.
I love being able to redeem my copy in more than one digital distributor, but i have to agree with you, thare are MANY people that abuse the system to multiply their license. Heck, even here on GOG we've already seem many people giving away/trading an unredeemed key after already reddeming it on another platform, such as Steam. Unfortunately, you can't have nice things, there will always be people who will abuse the system to get as much as they possibly can.
Well, about the games themselves i have to agree with what everyone else said. The market is currently saturated with platformers and Ethan seems to be just another generic platformer. If the game doesn't have anything to make it stand out from the others, it will be pretty hard to sell it. I don't think that the release of GTA V has anything to do with it. Both games belong to completely different genres to begin with. I doubt someone would decide not to buy a U$10 indie platformer just because GTA V came out. Yeah, Rayman Legends did come out at at the same time and it does belong to the same genre, but i don't know if it made that much of a difference.
Since i love platformers i would definitely get Ethan, but not at full price. Don't get me wrong, i would love to support indie developers, but i have so many indie platformers in my backlog right now (including some much more well received games such as Super Meat Boy, Giana Sisters and New Super Mario Bros Wii U) that there is absolutely NO reason at all for me to buy yet another indie platformer, unless it's in a bundle. I would love to support indie developers buying more games at full price, but the money i can spend on gaming is limited.
Now Race The Sun is a game that looks pretty good and very unique, but i wouldn't buy it, not even with a deep discount. I hate endless-runners, i just can't stand the genre. I don't like score-attack games in general. If the only objective the game offers me is to get a high score, then it's not for me. I do enjoy endless games like Minecraft and Don't Starve because these games do give me reasons to keep playing. In Minecraft i can collect stuff, build stuff, kill some monsters, explore the random-generated world. In endless-runners i just have to run, run, run, run, run, dodge from hazards, run, run, run. No, this is just not the type of game for me. And to be very honest endeless-runners do seem to be much more of a mobile genre than anything.
