How compatible are D&D 4th Edition and Essentials? Can you use Essentials encounters with 4th edition characters?
Here is my situation, I wanted to get my daughter and siblings started on RPG (11-14 y.o.), so I got the Dungeon Master's Kit, Monster Vault and HOTFL/HOTFK books. The only problem was that the books are in english, not our main language. I'm used to it and I learned to play RPG with english books so I gave it a shot.
The result was not so great. They got really confused about what was their powers and I literally had to read the all the descriptions to them.
Now, the Player's Handbook are translated to our primary language, together with the many pages of errata (the reason that I avoided it in the first place).
Can I buy the PH and give it to my players while I use the DMK and MV? What would be the expected problems and diferences?
