I have found online game to be VERY difficult. But, I'm getting close to 50 and messaging chicks in their 20s. Although, I have had some success. When I met them it's always been an SNL. But, getting that first reply is hell when all they have to do is look at your profile to see you're 20 years older.
In the field I can game young chicks with little problem, get numbers, day 2s and even few SNLs and men's room BJs. I suppose my personality is making up for what you can't put into an email.
