Which version of OFF is best for a first playthrough?

I want to experience OFF for the first time, but I'm not sure which version is best. I don't really want to get the paid Steam version, and all the free versions I've looked up consist of 2.0, 3.0, and 'Forgotten Dreams', the latter of which is apparently a newer retranslation. I want to get the 'original' experience, but if the newer translations get the message across better (whatever that may be) then I'd probably want to play those ones. also don't reply with any spoilers lol
