I thoroughly enjoyed them, i will say tho, that the flash caves were kind of an annoyance, wondering in on accident, only to find that I need rock smash (which isn't an HM, iirc, which means having to remember to never delete it from someone's moveset.) strength, and flash, to navigate them properly, the lack of a guard infront of the tin tower/ whirl Islands (Gen 1 had the guy block off cerulean cave) to tell you when to come back to explore them, granted you do need the specific wing item to make Ho-oh and Lugia appear, but still, I randomly found Ho-oh one day because I just happened to stumble into the tin tower. And make it to the top and was like whoah?! What is that?! And caught it with the master ball. Granted I guess that adds a level of explorability to the games, gen 1 was the same way, randomly going into doors until finding the one to go in, and even then it was rather linear. So some form of direction would be nice. I always hated that the whirl islands had 4 doors, remembering which one lead to lugia... wait I still don't know which one leads to Lugia
Also... roaming pokemon... why nintendo?! Why?! I will never forget bumping into Suicune right after it left burned tower (that patch of grass just south of the city, the one where you find stantler.) and thinking "this thing looks awesome!" Only for it to run, and me to proceed walking in that grass for like 2 hours trying to find it again, only to finally check the dex and see that it wasn't found where I was, which led to my general confusion. It wouldn't be until my friend got his nintendo power later that week that we'd discover they moved around at random everytime you changed routes. Still salty about that...
The "kurt" balls being generally useless and he'd only make 1 every 24 hours was another pain. But hey, at least ultra balls work better than great balls in gen 2.
Oooh yea! Bug catching contest, why the heck was winning that thing so hard? Looking at you Lass Beth, with your stupid caterpie that always managed to be like .000000000003 bigger than my catch, regardless of what I caught. I think I only 1 like 1 time in all the years I played that game.
I guess the level curve was bad? But I really don't remember any of that. Although trying to get a tyranitar or dragonite did take ages even with EXP share...
