The game is more than Terraria in space, but the ideas are similar. I really enjoy the crafting and quality of the work, and whole heartedly recommend for those into the crafting/survival 16 bit games. One little quibble I have is that the game has pretty low system requirements but cannot be played in emulation on a Windows on ARM device. I can play games like Torchlight 2 andGrim Dawn on the device, but Starbound always just says it can't run.
Yes, TQ started as a Greek themed Diablo 2 clone, but it was polished at launch has done nothing but get better. The new content adds a different vibe, and the new specialty plays different enough to make it insteresting (though I still love my Elementalist blend).
First, the game is brutal, you will die repeatedly. I'm talking like, give me another quarter repeatedly. This game has a curve set to the old school "get better or quit" mentality. However, it takes a bow to the new school in that with death comes the opportunity to buy incremental permanent upgrades for the next run. The graphics are beautiful, the controls fluid and the victories satisfying. All in all a good popcorn adventure space flyer meant for nothing more than the "I can get farther this run" mentality. Yes, there is a plot, but whether I make it through that is secondary to the fun of just basic blow them out of the sky shooting.
Titan Quest came out in the rush of games capitalizing on the Diablo 2 craze (yes, this game is that old). It lacks some of the polish of later games (e.g. Torchlight, Fate, etc.) but nails the formula pretty well for Diablo style ARPG hack and slash. The skills trees are varied (expecially with the included expansion), the graphics are crisp and the story different from the trite Western High fanatasy setting. I like the storyline and it has some epic moments.
