Honestly, I'm still more excited about Terraria patch 1.3, despite the fact that we still don't know much about it. The developer has posted a number of 'spoilers' which show interesting things, but there isn't a feature list yet. It's still several months away.
This looks a bit like Starbound to me, and something really bugs me about the Starbound aesthetic. As someone on Reddit put it, it's like those 16-bit era games that claimed to have realistic graphics despite being two dimensional - it just doesn't look right. I'll probably still buy it, largely because I've clocked up 91 hours on Terraria and paid mere pence for it (as part of a humble bundle that I didn't even buy specifically for it - it may as well have been a free extra). It remains one of my favourite games from the last ten years, and Re-Logic deserve more money.
