I never genuinely cared about MLS until last year. I watched the World Cup and other big games, such as MLS Cup, but that was it. When NYCFC came about I went all in on the sport and league. It's $65 now and goes up after a certain date. I watch probably 3-4 games on it a month, either to see stars on other teams or games that impact NYC in terms of the table. If you like soccer and MLS, regardless of the team playing, it's worth it.
Only downside is that all nationally televised games on Unimas, FS1, and ESPN are not on the MLS Live at the time of the game but can be watched the following day.
