Hi i've worked on like 6 unity games all of which are more complex. Which inclues the generes of multiplayer fps, boat racing, cricket game, arcade, and a kids learning app. So i'm really confident that i can finish this project for sure within the given timeline. But the problem is you are asking this for all platforms. And i do not have licence for some of them like xbox,ps3,wii. Anyway this is first project on this site and i'm from India too. Hope i will get a chance to work with you. Thanks in advance.
