I feel like these are all solid options, but I'd say:

1, 2 and 7 for starters.
I'd love to see a focus on Leo early on, it's a Leo backed investment after all.
Midterm I think most if not all of the above could and should be explored.

Personally, I like 5 a lot because I'm a sucker for crypto gaming myself.
I'm not the best Splinterlands player in the world, but I compete in Champion I each season, so I'd love to volunteer to pilot that part of the investment if we ever decide to go for it.
