FYI, Silver hates Team Rocket because Giovanni, his father, abandoned him because he wanted to train to regain his leadership of Team Rocket. (in HGSS, the Celebi event takes you back in time to the route beside Viridian, you see Silver and Giovanni arguing, and Giovanni runs off towards Johto). So that's why Silver hates them- also, he says it in Azalea Town after beating him, but claims it is because they're weak.
Anyway, I actually really like the look of this. The features are great- I especially like the idea of dynamic battles, it's much more realistic (I mean, obviously there'll be Pokemon of different strengths in an area, rather than just Pokemon all around the same level). I also like that it includes Kanto and Johto, but isn't a GSC remake. Kanto and Johto are great regions, but they could use a new story
