Had to think a bit about this thread. If you have nothing nice to say about 4th ed please do not post, if you love 4th ed this thread is not really for you but please feel free to post something. This thread is mainly for players who prefer other editions but did like something at least from 4th ed. THe reason? When WoTC designs a new system they have a habit of throwing the baby out with the bathwater. Star Wars Saga for example was a great system but not that much of it carried over into 4th. Very little of 3.5 carried over to 4th ed either.
One thing the edition wars posts have made clear over the last 4 years or so is that gamers do not like it when their favourite system they are passionate about is facing oblivion. Same thing as 2008 as at the time Pathfinder did not exist and the 4th ed players will have no Pathfinder for themselves.
However D&DN is going to need to attract gamers from every version of D&D. D&DN has 4th ed influences but it proably resembles pre 3rd ed D&D more than 3.5 or 4th ed. Broadly speaking there is probably 3 types of D&D player although they can overlap.
Pre 3rd ed.
Obviously you are not going to get everything you want in D&DN. Mechanics can change but one could aim for a 1/3rd content that at least resembles something one is familiar with in your preferred playstye. D&DN has 4th ed influences espicially in the monsters.
Put simply what did you like about 4th ed that you do not mind D&DN borrowing and will not push the grognard buttons to hard. I'll post my pones below so as not to have a massive 1st thread.
