With night game you get the benefit of a lot of nice looking women concentrated in a single area. They are looking for attention: Problem is they are dressed to the 9's and superficiality/narcissism is through the roof. It's not so much her, but her friends and other factors that can potentially get in the way that present an obstacle. You can overcome this tho.
The 2 main advantages of bars/clubs.
1. Number of women in a confined area
2. Knowledge that the woman is in the market for new penis. There's no point in going out to bars/nightclubs if you're not in the market for a sexual partner. Although some women like to be validated. Validation is easier online now though. 25 years ago, there was more of a need to go to night venues for validation.
In non-bar approaching, you can be on a walking path or in a grocery store for 2 hours and only see 2 viable approaches. There are more viable approaches in 2 hours at a bar.
Groups, biatch shields, superficiality, and narcissism are all downsides.
Honestly fellas I find day game far easier. They are out of their element and most men are afraid to approach (without liquid courage). It's very easy to swoop in if she is remotely feeling you and the approach is welcome. This requires you to always put your best foot forward - when you step out make sure you are looking good, walk upright/confidently, make eye contact, appear approachable etc.
I am well suited to non-bar approaching (aka daygame). I don't like staying up late at night. I've never had a good wing. I am capable of starting conversations without liquid courage. Some non-bar approaches are easier than others. A co-ed sports league would be easiest as you'd talk to someone at the sponsor bar after the league match of the week. Approaching someone after a fitness class is easy. General gym floor is more difficult because mostly everyone has earbuds/headphones. The grocery store is moderate. I found the mall quite difficult, though there's a way to do mall approaching. I could never implement it well.
Outdoor parks and walking/hiking paths have earbud issues and movement issues. There are tactics you can use to do stops, but it's difficult to capture attention and retain it for 30-60 seconds +. If you can get one of those approaches to 5 minutes, you have a good chance of getting a date from it.
