How much does game give you for games

Depends which game. A rarer, but popular game would give you the highest. Newly released games might not give as much as you'd think, since the shop will likely have a lot in stock and want to sell the full price versions while it's new. Unpopular and low rated games will give you the least. Unpopular and low rated games will not be purchased because they already have purchased more than they want. .

It depends, if it is good you will get a good amount, and if it sells well you will get a very good price. If it is a good game you will be amazed.
