So I'm trying the 10 day free trial and it's a really fun game but I was jsut wondering how many people lay the game?
I've gotten into a few groups (only level 3) but I just wanted to know how many people play at level 16 and how is the content and how fun is stuff at 16?

DDo can be great fun. I have 3 characters at level 16 now, although I've not played now for quite a few months - been playing World of Warcraft instead.

The main thing I like about DDo is that it has specific party roles for each character and jobs for each in most quests (ie traps and locked doors for rogues) whereas in most MMOs, the main difference is class is how you kill someone.

The higher level content is very fun, but it does get kind of repetitive after a while. There is a place called Meridia which came out in the last big patch before I left. Here you can craft items called 'Green Steel' items, but getting together what you need for them is a grind involving doing each quest in Meridia's surrounding area at least once (probably more often though, you still need materials), then going and living inside Meridia's raid (I forget what it is called) while you build up the ingredients for for each part of the crafting process.

The Vault of Night raid is fun. That's a series of quests designed to be started somewhere between levels 8 and 10 and finishing on the plane of night facing Velah, a red dragon. That is a very fun quest chain

DDo is definitely worth looking at, maybe get a month or 2 subscription to try it out properly. Eventually, you will run out of things to do though. The different character classes do provide a different view of each of the quests, but they are still the same quests.

If you get a chance before your trial runs out, go do the chain in tangleroot vale. You really should be about levels 4-5 to start it, but the chain will get you lots of xp, some nice loot, and it's really fun
