Got this game a while ago, took a literal ~5 year break, then came back to it recently by chance and beat it. Infamously easy, of course. Not a HORRIBLE game, but compared to the rest of the series, it severely lacks flavor. Just pretty boring. Easiest Champ fight of my life.

TEAM:
GRENINJA
CHARIZARD
JOLTEON
SYLVEON
LUCARIO
GOLURK (MVP for sure)
In-game time: 47 hours, 12 minutes

Out of a whim, I decided to play this game, and I ended up beating it. The only interesting parts compared to Red were seeing the different sprites. Oh, and the entire game being in Japanese.

TEAM:
(PAUL BLART) the BLASTOISE (yeah...I don't know)
(LOOP) the PIDGEOT
(KING) the PARASECT
(BROS) the DUGTRIO
(LATE) the FLAREON
(LOLA) the JYNX
In-game time: 13 hours, 22 minutes

Probably the most solid and complete Pokemon experience you can ask for. Gen 4 is the peak of Pokemon generations, in my opinion. One of my favorite teams I've made and used, as well as a crazy-intense champion battle against Cynthia (also the best champ in the series btw). Also, I got Pokerus during the grinding for the E4, wild.

TEAM:
TODD the EMPOLEON
GLUMP the LUXRAY (truly the goat of the run)
SCRAMBLE the TOGEKISS
KEN the SCIZOR
BAROCK the RHYPERIOR (I don't...know)
WEEKING the TANGROWTH
In-game time: 53 hours, 47 minutes
