I don't think I really need to say anything about such an old game, but it was fun to play in all of its broken balance glory. For instance, healing a burned Pokemon does not reverse the Atk reduction.
And one glitch I encountered way too often was the "Accuracy 100% move occasionally misses"
But overall, a refreshing, fun game. Also the first time in my life I caught Tauros or Kangaskhan in the Safari Zone, so cool there too. Really wanted to do the whole Tauros Hyper Beam spamming that was famous in Gen 1.
Gameplay time from Start to Beating Elite Four was 17+ hours. Didn't level grind, though the game is pretty easy with even the hardest enemies having bad move sets and stuff. I was 15+ levels lower than the opponent by the time I got to the final Rival battle.
Also, the Item Box is waaaay too small in this Gen. If you don't use the TMs, both the box and your pouch will be full by end game.
