The investment is in the investing into the game, not playing the game in my opinion.
But you can also invest time and money into games by playing (indirectly too via training courses) to get better and potentially give yourself a better chance of return.
just play your games and ,shut up :D
I think that the creators have played the game well for earnings :)
The games play themselves so I have time to do other things, like think about writing a post and then find something else to do. Perhaps a few comments on the posts of these creators you speak of are in order :P
What kind of game plays itself?? That isn't playing?
Worst date ever :D
Some of the investment type ones.
I can be, you just have to play me right :P
