Skill doesn't depend on the number of games played. Skill improves through analyzing your own games and those of others, analyzing standards, and so on. Simply playing two games every day won't help much. There will be some progress, but it will be minimal – you'll just reach your limit and stagnate.
No, Kostya... It also depends on who you're playing with. You can play with top players and learn in the process, or you can play with players of your own level, build a Capitol on turn two ;) and remain a noob.
But overall, the process of improving your skills undoubtedly requires what you mentioned.
