2). Modding Support. Face it, everybody wants to see an official tModLoader. However, we also know that Sony and Microsoft are rather staunchly against mods on their consoles. Some bigtime developers like Bethesda might be able to negotiate a deal to get it to happen, but it is always limited and very difficult, even for a big company like them to get it to happen, much less a smaller one like Re-Logic. So at the very least, if we ever did get modding support, we'd still have a separate version for PC, or, are we going to simply go "nope, no modding, sorry." because we're now trying to keep PC and Console/Mobile together?
Not everyone wants the ability to mod Terraria. Personally, I would like it to stay vanilla on consoles.
