My first New Order release was The Best Of...bought because it had both True Faith and Regret on it. :D
However, I found it really hard to get into...I loved the first 4 tracks, but Fine Time was a sticking point, and after that the songs just seemed to blend together (except Blue Monday...which I of course knew, but didn't know what it was called or who it was by...ahh ignorance
).
I've never thought much of World In Motion either...but then I hate football :p
Then I saw Crystal on TOTP2 I think, and I really liked that song, so I bought Get Ready, loved it, and set about discovering more of the New Order back catalogue by buying Technique, Power Corruption And Lies, and then later on Republic, Low Life (obsession triggerer), Brotherhood, Movement, and most recently Retro.
The more I listen to these albums, the more The Best Of seems like an incredibly poorly chosen retrospective...it's missing so much! Who on earth chose the tracklisting?
The Best Of nearly put me off New Order...kinda defeats then object of such a collection doesn't it?
