Any suggestions I make are things that I think would suit the game in question but not necessarily things I enjoy personally and may be freely used by any who wish to do so however I retain the right to use any of those suggestions elsewhere if I so choose.
If a developer chooses to make use of one or more of my suggestions the most I would like in compensation is a thanks in the games credits - something as simple as "Thanks to Suggestalot" is plenty - but I nether expect or require it for use any of my suggestions.
