I am a junior C# developer, working for half a year now. In my company I am working on some enterprise projects and after doing it for quite some time I understood that I dont like enterprise projects.

I have my own browser-game written in PHP+MySql with some simple HTML+CSS and I have 300 active (those, who entered the game at least once per 5 days) players currently :)

After thinking quite some time I understood that I am interested in:
1). Web-development
AND
2). standalone programs (but not enterprise ones).
3). Development for mobile platforms is also nice, Android/iOs.

1st and 2nd categories are what I want the most. Android/iOs is good too. I am NOT interested in big systems which are hard to integrate, I am not interested in enterprise systems.

In future I would like to start my own business/projects. I would like to create my own projects or/and create a small programmers company to create and release own products.

Please tell me what programming language(s)/technologies would you advice me for it? Thanks alot!

UPD: It's NOT a "which language is better" or any flame/holywar generating topic since I ask for language that suits my EXACT needs better. I believe C++ is better for low-level coding, while PHP is good for web-development and Object-C being made for iOs. I am still newbie at programming so dont hate me please.
