Go for it, I'd join. Just try not to go overboard with brand names.
I probably wouldn't go into that very much at all, seeing as no one would actually be able to read anything on all the bottle caps and trinkets they find.
Here are two questions for those of you who would be interested though:
1I'm guessing you would prefer a combat system centered
purely around Pikmin, and their strengths/weaknesses, like in the actual games.
But maybe there could be the choice/possibility for a little more emphasis on equipment. Upgrades for your spacesuit, and weapons of some sort to add a little more depth to things. Nothing too unfriendly to the lore/canon like Machine Guns, Grenade Launchers and such, but more along the lines of Miniature Cannons that fire the smaller bomb rocks, or an amplified whistle that could have a chance of stunning the enemy.
Most of the emphasis would still be on using the Pikmin themselves. Though you could choose to either focus solely on Pikmin Based Combat, or both Pikmin and Weapon Based Combat. If you chose to only focus your skills on using Pikmin, you'd be very effective with them, but you would be in trouble if you managed to lose your Pikmin.
If you chose to focus your skills on using Weapons and Equipment, you wouldn't be taking down groups of enemies on your own; You would still be using Pikmin to do the bulk of fighting. However you would be able to use weapons to support them, and if you managed to lose your Pikmin, you'd have a better chance at escaping from your enemies unscathed.
(Or maybe you have an entirely different idea for how things should work.)
2Should it be cooperative?
All of the players are new employees of the now prospering Hocotate Freight company, sent back to the Pikmin Planet in search of more Treasure.Or competitive?
After Olimar and Louie had brought back all of those valuable artifacts from the Pikmin Planet, other, rivaling companies decided to send their own explorers to loot the planet of all its treasure.
