The work done is trivial. With an engine, basic and ugly looking sprite placement is easy and the battle system shown could be hacked together in under a day.
The team needs:
- serious, committed programmers, because the Pokemon battle system is EXTREMELY complicated, I have tried programming one myself and got further than this guy but was screwed by small structural bugs affecting effect order on moves.
- artists and musicians. ripped graphics and music are not going to pass, and the current UI looks amateurish and not fun
- game and level designers who don't make miles of empty field that one walks through at a snail's pace. Pokemon is good because of very tight design work, not just because they threw some test maps together
Basically with a programmer's eye this is utterly worthless.
From what I know of fangames, do not expect improvement from the state of the first video and do expect the thing to fall apart as soon as school/life interferes.
