Why 5th Generation is clearly the (second) best:
Need i say more? yes i do, because i like to do that
-the designs of first generation were pretty crappy, and most of the Pokemon were uncreative, but hey, it WAS the first generation. so you can't really expect much. im not saying they are bad, but they aren't the best.
-Skipping second lets move on to third. some of the Pokemon are....interesting. the Pokemon themselves are (mostly) decent, but none of them are too great. the pallets are the main things that ruined them, because the third generation Pokemon all had darker pallets compared to the previous games, and since recoloring them would be weird, they have forever been stuck with those pallets.
-Fourth gen was MUCH better than third and introduced many great mechanics.i am glad they fixed the pallets and went to vibrant colors, as it makes the game look much nicer. a lot of the Pokemon WERE unneeded evolutions to previous Pokemon though, so it kind of didn't introduce many original Pokemon
- Second is best hands down. the graphics look smooth especially compared top first gen, the new Pokemon were original and creative, and it introduced Dark, Steel,and eggs. the locations were great, and it has the best soundtrack of any games to date. honestly, even the pseudo and regular legendaries were awesome. Ho-oh is beast.
-Fifth generation improved EVERYTHING. the battles are really smooth in these game,s and nothing like the demos or previous games. honestly, you could finish a 6 Pokemon trainer in like 5 minutes of battling if you are UNDER leveled. the way the Pokemon constantly move is neat, and the new moves are awesome. the game actually has a pretty involved plot, since you see a rival or team plasma every 10-20 minutes, and the game is pretty tough. the Pokemon also have the best designs in the series, even better than second gen, but second gen still has a better soundtrack
(i hate spell checker! it keeps yelling at me for typing Pokemon!!!)
