I'm a hoenn baby so I'm going to exclude the first two gens
3<4=5>6=7
Overall I still loved my time with Pokemon.
>>55162411BW and BW2 overall feel like more polished versions of gen 4 gameplay wise there's no gimmicks when it comes to its gameplay. You should give it Gen 5 a chance. I know a lot of people find the no old mons til the post game off putting but I just love the games unique overall aesthetic.
