Nothing has actually felt like Pokemon to me since Gen 2. Gen 1 and 2 are just well made graphically impressive 8-bit games. The rapid jump to a 32-bit platform hurt the series, because the gameplay didn't evolve past that of an 8-bit RPG. Gen 3, and the next few gens after it, don't do enough to innovate the gameplay, you're still surfin and getting in random encounters and fighting gym leaders and fighting some pokemon gang. Basically, it's what this anon says:
>>55319235R/B/Y and GS are top tier GB games, but everything afterward is mediocre in terms of gameplay and graphics.
Eventually, you realize all the pokemon remakes aren't worth playing and you should always play the original release.
