Why did you get it without the expansions? Imo the original game was quite short and for the original price (which you probably didn't pay) not worth it's money. But with several expansions it's grown quite a bit. It lacks end game content, but you can have a good time for quite some time now. Especially if you play less than some other people.
Not sure if base game vs expansions allow it, but we could play together if you'd like. Though time differences will most likely not make it easy.
As far as me being good: It's much easier to look good when you edit out the bad pieces.
In all honesty i do ok and am above average, but by no means am i very good (my k/d score is usually around top 34% so just going by that 1 in 3 players would be better than me).
Even though it takes quite a bit of time, it was nice to make. And i actually have a few other clips with throwing knives saved so maybe some day i'll do another. Although i don't play gunslinger much so if i want an all throwing knives montage it'll take a while. So perhaps a mix of nice plays would be more in order.
