Wizardry is a series of games that started in the early '80's. It's basically the granddaddy of every single game that has a forum here. The game it's most closely related to is Wizards&Warriors. Wizardry 8 is what will be the latest installment in the series. This will be the first sequel in the last 8 or 9 years. A compilation of all the previous games was made about 3 years ago (although I haven't been able to get my hands on it
).
I hope this info was sufficient. Let me know if you need more!
