I had a not-so-legit copy of warband for ages, enjoyed the single player quite a bit.
So I had a look for some mods and found cRPG, installed it and hopped on a server, but had no clue how the whole thing works. (For some reason my pirated key worked on cRPG)
Now I know that I had been on DTV, I asked how I could get better gear but no response. So I left and did not return until about a year later or so when I bought Warband when it was on sale.
Then I rediscovered the mod.
I then actually figured out how it works with the help of other players and got into it. (Though it was tough since I had only played Singleplayer up until then, and that only with cheated stats so I was almost as op as the chadz bot on HRE dtv
(Nah, was actually even more op)
So I never had to learn how to play properly, until I started playing cRPG.
Now I am still here and realise that this is a fucking deathtrap and I wish I had never rediscovered it. Too late now though, can't stop.
