>when does "newpokémon" start?
it starts with Sword and Shield (generation 8) because they came out on a current gen console (the switch).

>what does "oldpokémon" mean?
answers will vary but i'd say if a pokémon game came out on an old gen console then it can be considered old.

>what are the top 5 pokémon games?
(in no particular order)
-pokémon crystal
-pokémon emerald
-pokémon platinum
-pokémon heartgold/soulsilver
-pokémon black2/white2

this top is based on both my personal opinions and on the general consensus.

>If pokemon xy sunmoon are the worst why are they the worst ?
to make it short, X and Y were the first games to have a fully 3D interface and the jump didn't go smoothly (among many other things)
for Sun and Moon what is criticized is how easy the games are

>Also what games should i play? All i have is a mac x and Nintendo switch

here are the games you should play in order
1-pokémon fire red/leaf green
2-pokémon emerald
3-pokémon platinum
4-pokémon heartgold/soulsilver
5-pokémon black/white
6-pokémon black2/white2

these are commonly known as the classic era pokémon games (before the jump to 3D) and you can easily emulate them on your computer or phone.
but since you have a switch you can also play all the new pokémon games instead.
