I've been binge playing Starbound every day for almost a week, now. I got into it, and now I can't put it down.
The game combines far too many of my favorite things into a good game.
2. Exploring neat and interesting places
3. Full customization
4. Great co-op
5. Mystery and intrigue
6. Explosive weapons
7. Mad Science (At least, there was the illusion of it. It's not as fun to be a mad herbalist as it is to be a Victor Frankenstein class scientist, like I thought I was going to get to be.)
That's a big reason I got so into LittleBig Planet. It had some of what I listed above. Minecraft and Terraria were much the same way, though Terraria held my interests longer than Minecraft. Most likely because within the first three days of playing Minecraft, I had seen all there was to see, and done all there was to do, due to it being beta 1.7, and from there, it didn't take long for me to start realizing that there was no substance to the game. Once you'd been to the Nether, had a full set of diamond armor, with matching diamond tools, that was it. No amount of gimmicks and pointless additions later on, helped in anyway, at least, for me. Once I had experienced the new addition, the game went back to feeling empty again. Sure, I did the epic builds that other people did (My most elaborate build was a castle on a platform that was being held up by two giant obsidian dragon statues. You had to enter the foot of one of the statues, climb all the way up it, and then you could reach the castle.) I even tried to be nerdy. I built a gigantic questionmark block from Super Mario 3, I even recreated the Rusty Bucket, to scale, from Banjo-Kazooie. I made a mod, I played survival maps, I got a little more game out of the Dragon Block C mod, but even that was a shallow experience. Becoming a Super Saiyan, and having a power level of over 9000 were the only highlights. I lost interest trying to battle the Ginyu Force, after I found out the game was so incomplete that running along Snake Way was a 5 minute waste of my time. Even hunting the dragon balls became tiresome. The wishes weren't worth the effort of collecting them more than once. Terraria at least added purpose, by having bosses, a dungeon, and a progression, but even that wore off once I was strong enough to take on hell. Sure, I beat the Wall of Flesh, and hardcore mode made things tough, again, but I didn't feel like I was getting anything out of it. It was still all the same, just harder.
Oh, that was a tirade... back to Starbound. I've been playing it constantly, and there's just so much content. The FrackinUniverse mod only compounds the problem, too. I've been playing with a friend of mine, and one time, I found this dark planet that was made out of rotting flesh and organs, so we went to it. It had hideous, monstrous wailing in the background (had the music turned off) and when it rained, it would rain blood. The lakes were made out of puss, and the whole time we were there, we were slowly dying due to insanity. Another planet I found was all ocean, except it was all poisonous, and another still was a sulphuric ocean planet that rained sulphur. There was one that was so fiercely hot, that even our extreme heat protection couldn't protect us. We still have yet to figure out how to land on that planet without immediately dying.
In closing, I'm hopelessly addicted to playing Starbound. It's taking a lot of time out of my game development, but it is a learning experience. I honestly wish I had played Starbound before I started my game project. I learned some stuff, through playing, that could have helped improve the game.
No sense in starting over. If I did that, I'd just become discouraged, and may not be able to finish it any time soon. Of course, I wouldn't be too bothered by quitting, but I can't say the same for people who are waiting for me to release a game.
