I support your idea overall, but I think it could be greatly improved from hard data. Sounds like there are two underlying hypotheses to prove:

1. SPS is underpriced relative to its maturity and utility, because of how difficult it is to obtain given the obscure chain and no CEX listings.

2. A growing token price is the most effective marketing tool in crypto in terms of encouraging new players.

In my opinion, both are true - but some suggestions on what we could do to validate:

1. Examples of price action for other in-game tokens pre and post T1 CEX launch.

2. % of signups that joined within a SPL "pump" month (i.e. mid-late 2021, for example). The higher %, the more we can validate both hypotheses.

3. Current monthly active users that joined within a SPL "pump" month. This gives us insight into stickiness of said users.

The only untestable statement is: "Listing on a T1 CEX is the best use of funds." That is completely a matter of opinion.

In my view, it should have been done years ago and is simply table-stakes for modern web3 games - as long as it does not bankrupt the DAO, I would place it at a very high priority.
