>>56222322>What do they do that others don't?Multiple battle formats for starters.
Shinies giving you incentive to catch multiples for personalization.
A baseline of 400 monsters without dlc/transfers as of gen 4
Take that last one and factor in the fact that regional forms aren't considered their own mon in the dex unlike most tamers and that 400 count increases.
Recently, raids. Before, battle facilities with record keeping.
Marks, ribbons and titles.
A fair amount of non battling minigames
Not making stat items absurdly rare or expensive
That's just off the top of my head.
