Sick Michael did a walkthrough for Pokémon Yellow! More like a playthrough, really. I played the game for the first time, while sick, and I got all the way to Brock before I hit the wall where none of my characters did any damage.
Having never played Pokémon before, I'd say it's okay. The main problem is that the game clearly expects you to know everything about Pokémon ahead of time, which is massively unfair. The game punished me for trying to break trainer battle rules, and I have no idea what a trainer battle is or what the rules are, why is there no tutorial on this?
I'm sure I made a bunch of bone-headed newbie mistakes, like pick the wrong Pokémon to be on my team, just because I don't know any better. In my defense, it's kind of hard to pick what Pokémon should be on your team. Like, obviously you want the best team ever, but you don't get to see character stats until AFTER you recruit them. That's not very fair! Then again, I don't really understand the stats anyway, so...whatever! I think I got a good team.
EDIT: I'm told the goal of the game is to collect all five badges, from the various gym leaders. That way, you can enter the tournament and face off against the Elite Four, the best Pokémon trainers in the entire world. That sounds kinda cool! Too bad that wasn't explained in the game itself.
