What system have you bought the most games for? Would you say it is your favourite system?

[Conina]

PC by a long way: over 600 retail games, over 600 Steam games, over 80 GOG classics, some Origin and U-Play gmes.
Followed by over 700 iPad games (free games already excluded).

Consoles & handhelds only 20 - 50 games per system (without PS+ games), since I prefer the PC versions of multiplatform games.
