Do we need instrument for exchanging video games?

Hi all.

I have created Android app (it took 4 months) that will help us exchange our video games (for consoles: Playstation 4, Xbox One)

I'm looking for community opinion: should we (gamers) have such instrument? Because I have small concerns about it. Please leave your comments here, if you like idea or not, and why. Thank you!

"Want to Trade" or "WTT" is project about exchanging video games and this application is your main instrument for searching, discovering and finding fellow gamers near you. Can you imagine people around you who also love to play video games? Now you have ability to know them all and exchange with them.

Google Play

How it works:

1. Add games that you have, add games that you want.
2. Visit any game page and you will see who has or want game
3. Want more options? Use search and discover gamers around you, analyse their games and what they want.
4. Meet and exchange ;)

If you have any questions, don't hesitate to ask ;)

Thank you.
