2nd post.
2 cents.
If you want to have fun playing a role-playing game, play with people you like. Systems are optional. I have enjoyed and hated every system I have played. It all came down to the people and the story. Broken mechanics and things you don't like can be side-stepped or outright ignored. One thing every rpg I have ever played has always stated in the game is "do whatever is fun, and if a rule isn't working, don't use it."
I'm currently running two systems - pathfinder (I'm a fan of what they have changed from 3.5) and 4e (I'm still learning, and I like a great many things, but if I hear "twin-strike" one more time I might vomit...).
I am enjoying Pathfinder as it is comforatble and I have essentially had 7 years of 3.x to get used to it.
I am enjoying 4e because man can I whip up encounters quickly, and everyone gets to do something, every round.
New systems are always tough. They are like new cars. You test drive them, and they smell nice, and look nice, but it isn't until you get them home that you realize they don't have as many cup holders as your old car, and the place where you keep your change on the dash isn't there anymore... but the new car is so fast! And smells nice... and there are no food stains from where the kids... never mind. You get my point.
One thing I can agree with whole-heartedly is that the stock adventures suck ballz. I tried running the forgotten realms something-of-war path and the first adventure was one of those completely disconnected dungeons where the family crypt has fungus and drakes and the gnomes live there too... it's like something reached into the monster manual and just ripped out pages at random and said, yeah, since we don't have favoured terrain any more, this will work and people can suspend enough disbelief to enjoy this... yeah, that's it. Garbage. Absolute garbage. Even dungeons should make some sense. Undead and orcs don't live happily only a room apart from each other without some sort of controlling shaman or magical trinkets or wards that keep them apart. It's like, "Morning Ralhp," and "Morning Sam..." and let's just clock in and out like we do this every day and nothing is unusual about the situation.
I do find for 4e it is a bit of a challenge to handle all of the old mundane stuff that 3.x could do, like profession checks and craft checks. I end up defaulting to whatever a character does best for the most part and hoping everyone buys into it "yes, acrobatics does help you steer a ship at sea, why wouldn't it?"
Anyway, enough blathering from me for one post. Just play whatever, as long as you play and have fun.
