Honestly? Not that much. Maybe some Safari Ball Pokemon you don't already have, but most of the special Pokemon are unavailable outside of exploits or third party software to receive the gifts. (particularly as Game Freak embraced just giving people the special Pokemon rather than letting them catch the Pokemon themselves) And IIRC, Cosplay Pikachu cannot leave the game it's obtained in.I'll have some much needed free time next week after lots of classes and traveling, and I just want to rest. Was thinking of going back and playing some old games on old DS. I have Emerald, FireRed, Platinum, Soul Silver, White, White 2, Omega Sapphire and Sun. I also have Ultra Sun but most of my stuff is on that game so I won't start a new one.
I'm big into collecting (I have a near complete living dex, over a box of shinies, comp. pokes, apriball collection, etc.) what do you think the replay values of these games are from a pure collecting standpoint? Which would be the most and least valuable playthroughs? Obviously legendaries, and maybe Apriballs in Soul Silver, but other events, mechanics, special pokemon, etc. that are make any of these games especially worth it?
It may be best just to enjoy the games rather than fret which has the best replay value for a collector, particularly as I would think you would have obtained everything you could the first time. (or jump back in to snag what you missed and can collect) But you do you.
