Personally, I prefer AD&D over 3rd edition D&D. Besides, out of the 3e D&D video games I've played, one was alright - Icewind Dale 2 - and the other ones were to a varying degree catastrophic - ToEE and the NWN games.
As for the Blackguard kit, I'm not sure if not being able to achieve mastery and grandmastery in weaons is a fair trade for those perks...
