Why do people like this series so much? To me it seems like a standard JRPG. You collect a party. Grind a ton to level them up and gain abilities. Then take down enemies with that party.
Except it lacks the story aspect almost completely.
There are two problems with JRPGs:
1. The stories are generally love them or hate them. As a westerner, I always feel like something is lost in translation, resulting in some strange storylines (See my favorite JRPG series,
Kingdom Hearts).
2. The combat system is ancient. I generally avoid JRPGs because they use turn based systems for combat, grinding the action to a halt, and the fancy animations only make the turn taking more frustrating.
Pokemon, IMO, improves upon JRPGs by minimizing the story elements. You have a set of goal, but you don't really have to pay attention to the dialog beyond finding the next whatzit to continue. It also improves upon the combat system by letting you build your own team from hundreds of available "characters." There are, literally, thousands of combinations that all work. That, I think, is probably the biggest appeal to the series.
And to the conversation as a whole, I think the Gen 1 > Gen 2 jump was the biggest in terms of value. There have been some good system upgrades since (which is why I enjoyed
FireRed and
SoulSilver), but I'm always put off by the creeping number of Pokemon. I would much rather see the same faces with new battle systems than 100 new pokemon including 38 new legendaries...
