I feel 4th gen is really pushing it from being different then the other gens. If I had a favorite gen it would be 2nd that was when Umbreon and Tyranitar came out lol. Who doesn't like 3rd gen? that was when Blazken came in. If you started when red & blue came out you won't want 5th gen makes me think of space age style which is just wrong.
I am debating on if I should even get 5th gen. Of coarse I have not gotten it, because it is too different from the other gens. I've been playing since the beginning red & blue. I got them pretty much has soon as they where in stores.
