A casual player like myself cannot keep up the pace like GW has pumped out so many new books and editions lately. And to be honest, I do not want to spend 45€ for each army every three years for the codices alone!
At first, I thought about playing 2nd edition 40k, but some of the newer factions were not present at the time as they were later on. The unit choices/datafaxes were pretty limited, too.
Sure, the 5th edition isn`t perfect, but it is a concluded system and will always stay this way. The rules will not change any further! We`ll see how it will work out.
I look forward to playing my next games and painting some miniatures! In fact I`v already played two small games (40k in 40 minutes) with my son using the 5th edition ruleset... I'm hyped!
