Working with textures, using Modloader also having a lot of time spend on fixing stuff you’ve already fixed in Minecraft with your own modding tools. Yes it looks like a pain in the, but still it’s worthwhile once it’s finished. A progress in making a mod seems like it isn’t moving sometimes, but then out of the sudden an huge update comes out that surprises a huge number of users on forums, chat’s and reddit-like sites which make an Mod for a game pretty popular.
Having a website, with a forum is a must have since there need to be a place to update your fans, and publish new stuff for free we hope, since all gamers payed the game why the mods then, off course everyone works like this and hence why we love the games with mods.
Some creators even face problems like, no blocks guys, it’s not Minecraft, but hey everything get’s worked out and fixed in the end, since they know the best when they create their own new stuff for us to play in our free time which we, lately don’t really have, but we try and try to get it to play some more of fresh content for us. When does it come out, is the question which modders hate the most, since they don’t even know.
