I'm personally prepared to cut Spartan plenty of slack. My group of friends just play the original rules and haven't really had any problems. But then we're pretty much the antithesis of your stereotypical, fat-beard rules-nazi tournament-gamers so
YMMV.

(I have to admit here that we are pretty terrible when it comes to rules - we'll come across a situation and if both sides agree as to what seems like it *should* happen we'll go with that rather than even bothering to look up the rule... we're lazy that way! Only if we disagree, which doesn't happen often, or genuinely don't have a clue - which happens more often

- do we bother checking the book. If we still can't work out what to do we'll flip a coin and get on with the game.)
They're a small company, surprised by demand (their moulds have worn out and had to be recut far in advance of expectations) and learning as they go. I understand that they also had a horrendous computer crash a month or two back, which set them back while.
For us, in our group, we just ignore the forums and play by our own interpretation of the original rules. I appreciate for some who like official rulings on everything, trying to navigate the labyrinthine maze of the Spartan forums can be a trial, but ... each to their own I suppose.
I am irritated in having to wait for the Dwarf submarines and for Firestorm, but that aside, my nerd-sense isn't tingling with much irritation.
Give them another decade, and once they are multi-national corporation with a £multi-million "development" spend, then maybe I'll be less forgiving! As things stand, with a pretty solid printed rulebook and downloadable pdfs for most "important" tweaks (anything that hasn't made it to PDF should be discounted as
de facto unimportant
IMHO) they are still streets ahead of *some* large wargames companies I could name...
