I agree, Terraria have always be free content and you have to do is just wait until the update is finished.people calling terraria "unfinished" when it was a complete game at 1.1, and every major update since then has only made it bigger and better in every way, all for FREE... is honestly frustrating.
especially when so many games out there cost $60 and have chunks of content literally removed/locked and sold later for almost the same price.
terraria IS a finished game, and the people behind it have shown a level of passion for their creation that i've rarely seen over the past several decades.
But in Terraria case, the game is finished, what do you else is going to happen. Last year's (2020) Re Logic said themselves the game is finished contant wise. They mostly likely will continue developing game for JUST bugs fix's or anything else small. (For example more weapons and accessory balance changes) Not game changing like added more bosses and more biomes and anything else big) By the way why else do you even want? Tmodloader is the game future which means moving forward you want something new play modded. It is easy to do that and free. Re Logic is ending support for vanilla game. Stream Workshop and Tmodloader is the game future. Modders are next type of developers. No longer Re Logic.To me it's somewhat the same thing. I also think it's an unfinished game. But I'm thinking more about other things.
