I'd like to create a simple multiplayer game designed around a single asset, you could call it tokens or bullets or power points, but I find it difficult to come up with some very core concepts. Now I'm looking for inspiration.

I'm thinking in terms of a command line game in terms of simplicity and the way you'd play is transferring your assets to someone else, or to a pool or a "duel". I want to run it on a blockchain if that helps to understand.

My main issue is figuring out how not to hoard the tokens and instead use them to fight or collaborate with others.

No I don’t think you need single assets only while creating a game. You are thinking to create a multiplayer game, which may include various things like, visuals, ideas, logics, sound and many more. So you should be ready to use more than single asset. Because it’s better to work in a proper way to deliver a good result at the end. It will be time taking as well.

Pretty sure he means assets as in game currency or other items.

I can't really think of any examples, generally there are many things id consider assets in anything more complex than like a simple one-round card game. e.g. beyond that you might have points, but now I have two things, my points (which maybe I could use for bets and thus have the potential to loose them, like say Poker), and my current hand of cards. I guess if I did not have my own hand, and was just placing bets on something else outside my control its a single asset, but not sure id count that as a game.
