I'M SO ADDICTED TO TERRARIA AGAIN LOL. The 'new' world with new areas is so much fun, exploring is so addictive, etc. Especially now that I fought through to get me a thorn chakram (I can't believe I went through jungle with a golden sword! It can be such a pain in the ass even with chakram) and I can kill stuff with relative ease from a distance.
And house building is fun too, even if my will to use All The Different Materials makes it a random mess
I think Terraria for me has gone from "a fun little game that's worth buying when on discount" to "insanely addictive quality game that is well worth its original price" (10 euros on Steam, if it's 10 USD then that's even a better deal)
Now I only wish we could have a group server together, it'd be fun to explore together, help the newbies get better gear (even if my gear is not that great yet either! lol) and I guess do the bosses as well, but that's actually not as important to me
