It's really hard for a game to interest me, to be honest my most suited playstyle nowadays is to go AFK in an MMO. I also easily get bitter with game developers, for all intents and purposes I'm a horrible videogamer these days. But I can't put KSP down, I sink hours into it without noticing. I can't put my finger on exactly what it is or what combination of things is doing it, but I love it!
