OK, so a bit of information for tonights game.
There was actually two editions of AD&D (1st and 2nd, with the first edition released running in parallel with OD&D), but the changes between the two are fairly minor, and @H, @S_journ, and I agreed that if we play all versions of OD&D/AD&D it will take a while, and there isn’t enough differences for it to be noticeable.
As such, I’ll actually be running 2nd edition, the main changes to the first was the fact the books were better organised, the removal of several character classes, and the removal of lots of references to demons/devils (due to a slight media perception problem (A)D&D suffered a lot during the eighties).
The main thing about the 2nd edition AD&D era - it was all about campaign settings. During the 1st edition/eighties there were three settings: Greyhawk, Forgotten Realms, and Dragonlance (all fairly high fantasy). With the second edition TSR started producing a campaign setting every year: Spelljammer, Ravenloft, Birthright, Dark Sun, Planespace etc. to not name a non-exhaustive list, each often with its own slight rule changes and a slightly different theme (Spelljammer was “Science fantasy”-ish, Ravenloft gothic horror, for example). So, therefore, we will be playing an adventure in one of those settings, with the slight changes to rules it introduced.
I’m aiming for a slightly higher level (4/5), so I’ll bring pre-generated characters. If anyone wants to create characters then I’ll be there shortly before 7, and as @OddlyEd is unlikely to appear before 8 we will have time to create some.
