Now that you've played the Hack 'N' Slash games, you'll find it easier to play the AD&D's.
The main differences are:
1. You always pause the game before and during combat. You can't hack 'n' slash you way though them. You pause, issue commands to your party, watch them carry out their orders, pause and issue more until you win the battle.
So the comabt is a lot different than what you're used to. If you can handle this, then you'll be fine. This is the main problem for most people making the transition from Hack'N'Slah to D&D.
2. Weapons, armour and "chance to hit" become factors. The lower the armour class, the better. There are different abilities as well.
3. Gameplay is gerenally much slower, as the D&D games are more story orientated. You can have the same battle 10 times before you defeat your enemy, with all your party intact. This calls for more thinking during battles, as opposed to rushing in with brute force. The quests are more involving; the story, politics and religion more complex.
This is just basic information, and it isn't strictly true. But I'd tell it to you this way to simplify things. Most people try to use their Hack 'N' Slash techniques to play, and it doesn't work. They become frustrated and lose interest. Think about your attacks, and rest often.
Just remember, don't expect to be rampaging through the countryside and you'll have a world of new RPG's to play. <img src="/ubbthreads/images/graemlins/smile.gif" alt="" />
One other thing...
You don't really need to know about all the complicated AD&D rules.
