Technically, and in terms of the match engine, I'd have to say NSS4. I really enjoyed my fledgling career before the 1 laptop I could play it on met an unfortunate end. But there's something about NSS3 that makes it a little more 'cosy' and easier to get on with I think.
As much as the text games were a welcome break, I couldn't go back and play them now
Close call between 3 and 4 then, where I'd probably plump for 4, purely in terms of the advancements made on 3 in terms of engine and interface.
