-the concept of a large number of creatures, instead of x classes
-type relations are a base of almost every combat
-random encounters are limited to grassy areas (except on caves)
-Vaporeon is lovely, It had to be said
did not like:
-overdoing some of the "multiplayer aspects" when the technology just was not yet
-the sort of elitism and science going around it to have the best teams, seriously, it is just too much for me
-shinies, most useless things since the splash attack, I prefer not catching a pokemon if it is shiny because of how weird people are with them
-leveling up can be a bother since wild pokemons are low levels generally...
Game design is all about decomposing the core of your game so it becomes simple instructions.
