Well, I was all set to buy Metroid Samus Returns and maybe Xenoblade on 3DS, then it hit me...
I... don't like playing on the 3DS. I don't think I ever have, whether on my original XL or my small N3DS. I have several games on it I still haven't finished - haven't even gotten more than a few hours into Majora's Mask since I bought it in January.
And it's not because the games are bad, they're great. But fuck if I wouldn't rather play on my DS Lite or GBA.
It's that fucking circle pad. I hate it.
So what to do? I still have quite a few 3DS games on my wishlist, games I want to feel my collection is "complete" in my eyes. Games I really want to play. But I feel like I just won't play them because I'll keep playing games on my Switch or PS4, or even my Vita, because it's a more enjoyable experience.
Off the top of my head, these are the 3DS games I still don't have that I want:
Metroid
Xenoblade
Fire Emblem Echoes
Mario & Luigi SSS remake (love the original)
Fantasy Life
Radiant Historia
Kirby Planet Robobot
SMT Strange Journey
SMTV-2A
Culdcept Revolt
BoxyBoy Series
Rhythm Heaven Megamix
FF Thearhythm CC
Kokuga
Pokemon Sun Ultra (maybe, last I bought was Y, didnt finish it)
That's a ton of games! Great games! I just don't know if I want to keep investing in hardware I don't enjoy using.
By contrast, here are the games I have or had.
Fire Emblem Awakening
Mario Kart 7
Mario 3D Land
StarFox 64 3D
DKC Returns
SMTV
Animal Crossing
Mario Golf
Zelda ALBW
Zelda OoT 3D
SMT Devil Survivor
Etrian Odyssey IV
Super Street Fighter 4
Kid Icarus Uprising
Resident Evil Revelations
Resident Evil Mercenaries (ugh)
Prof. Layton
Pokemon Y
Senran Kagura Burst (ugh)
Project X Zone (ugh)
Ace Combat
Dead or Alive Dimensions
Mii Plaza Game DLC
Pushmo
Pocket Card Jockey
Shantae & TPC
Cave Story 3D
Gotta Protectors
The best Guild01 games
A bunch of other eShop exclusives, 3D Classics, etc
So as you can see, I've already heavily invested into the console. I have a nagging need to "complete" my library, at the very least get 3DS-gen representation for all the classic Nintendo franchises (Metroid, Kirby, etc). And i feel especially compelled by the oh-so-rare sale prices.
But I could also just buy more Switch indies, retro shooters or get Dragon Quest Builders, Mario Aces, Ys VIII, Dark Souls, etc.
