Words & Rules . . . . . . . . .
Thats what its all about isn't it - 'shaping' your Game world with Words and with Rules.
What I plan to do with 4th Edition is put back some of the ideas I (and my Gaming Buddies) enjoyed from previous editions of DnD and ADnD.
Multiclassing done 'Old School', a new Version of our Old 'Critical Hit' System, Hit Dice at each level (after the first) rather than a Static Hit Point advance, MORE skills - rather than just the small 'Adventuring' Skill selection in the current 4e Rules.
I really like 4th Edition, but there are some elements that need 'tweaking' for them to fit into our style of play.
