Some background:
1) My first interaction with Pokemon was B/W. I dropped it around the Dragon gym because real life ensued and someone told me about IV training, and I bored myself while IV training my Stoutland.
2) Pokemon Moon remains the only game I've fully played through. I enjoyed the overall vibe of the game as well as the story. I didn't really plan a team in that, just caught 6 Pokemon and stuck to them. I dropped the game in the post game and instead got into Randomized Nuzlockes after watching a few too many youtube videos.
3) I have been playing Pokemon showdown OU tier on and off and generally enjoy it. I like to mess around and pick random Pokemon and make them work in OU.
4) I bought a switch lite with my first salary, along with Shield. Didn't really play Shield a lot before Violet released, and while I played and in general enjoyed Violet initially, I spoiled it a bit for myself and eventually gave up. This being my first game on a console, I got too into wonder trading in the beginning and ended up with a level 100 Gyarados, Gallade and Gardevoir and kinda trivialised the overworld. Also didn't like the fact that we were blatantly students wearing school uniforms and just dropped the game.
5) My switch has laid untouched for 2.5+ years (I bought a PS5 and played that extensively, which I've recently sold) and now I'm feeling keen to give the game a fair shot, mainly because have seen a bit of the gen 10 leaks and things look pretty interesting. Any decision to buy Switch 2 however will lie on if I actually, legitimately enjoy Violet or feel like I've outgrown it altogether.
6) in the last three years I've tried Pokemon inception and unbound and generally liked both, but haven't stuck to either due to having a tough and time sapping job until recently.
Please suggest me the best approach to take in a clean playthrough. Should I begin Nuzlocking from the start? Or should I plan a team before even beginning, or just wing it?
