Would this really make that much of a difference?
In my view of things yes. The strategy would be to make more uses of LEO token. So, imagine that we have for example a "exchange" game... where you can actually have "competitions" and those competitions will have LEO awarded, and require you to get in with let's say... 1 LEO... then if there are 1000 people playing the game... there 1000 LEO to distribute for the winner.
At the same time, because its a game, people will be less afraid of loosing (because it will be with non real tokens....) and train them on how trading would work, what things can happen, etc...
I have lots of other ideas... and to be honest, most of this is even already done... look at LEO Dex :P
RE: Is there any sort of reason why LEO has no investment game?
