OPINION ALERT: Not including the Meta game, X/Y is quite easily the worst set of Pokemon games yet.
In no way terrible, but:
1. Predictable, non-sensical storyline.
2. Boring, generic ''freindly rivals'' who aren't remotely challenging.
3. No Negotiation trading
4. Poor post-game story.
5. Laggy battles.
4. Permanent roller skates attatched to your fucking feet.
5. Like, literally ZERO fucking character development except for a 9 year old coming on to you at some point.
6. Useless, useless Mega Evos.
7. Fedoras available to buy in nearly every store.

Gen 5 was the last Gen to remotely interest me because I felt I could actually take it seriously. Pokemon has gone from a story-rich battle RPG to a children's game full of pointless fan-service.
