my main problem is that red and blue are basically unplayable now. The games have upgraded each time, adding new thing and taking out nothing so thats like saying a straw house is better than houses made today.
also, the whole 'Pokemon look stupid now" argument is basically a joke. every new pokemon is either 'too simple' or 'overdesigned.' its like they dont realize how simple the designs for voltorb, diglet, grimer, etc are or how designed pokemon like magmar, jynx, Mr Mime, etc are. theres good and lame pokemon in every generation so grouping them all by the whole is just trolling. Ill admit there werent alot of Gen 3s i liked but some are now classics. Honestly, i would rather have more detailed pokemon than simple ones. the only reason they were so simple before was graphic limitations. Im sure gamefreak always wanted pokemon to be multicolored.
TL;DR: red and blue are outdated and the whole "new pokemon look bad" argument is bologna.
The fact that you have to criticize at all is amazing to me. Can't you just lose interest and leave it at that? Do you really have to make everyone else try and lose interest too? Is it your goal to have everyone liking the same thing?
