Skins, media packs, servers, hosted realms, upsales through all consoles, multiple copies for multiplayer with/between your kids… also a mass revolving shit tumbler of account stuff on the backend that invalidated lots of old accounts…
I bought during the beta for a lifetime of goodies, had to buy it again after the buyout, then again after an update to MS accounts wasn’t acted on, and then for the Switch. I’ve bought Minecraft 4 times, with another on the horizon if it keeps popular.
all of that except realms is bedrock edition, not the java one. I'm honestly pleasantly surprised they haven't killed the java version
