I suppose I may update the situation. I still play Future Tone DX almost daily (although I've kinda played it through already w), occasionally I might play Diva X too.I used to play a lot when I was a teenager. Nowadays though there's work and all sorts of other stuff to keep me busy. These days I mostly play Project Diva games (Future Tone, X and F2nd), with Driver San Francisco and Gran Turismo occasionally. I used to play a lot of Call of Duty etc. on PS2 but my PS2 is currently stored in a closet due to lack of space.
Out of mobile games I only play Moe! Ninja Girls (my phone is quite old and can't handle most games that require more RAM).
