Starbound (and Terraria) was something that I had a bit of a crack at ages ago... I really like the idea, but I just can't get into the 2D platformer thing.... Actually, I've never really gotten back into platforming since Mario on the SNES.... not entirely sure why, but I really wanted to like this game....
I did not think I would enjoy 2D either until I started playing a couple. They have started to grow on me.
