I don't see any effect change. They're already adapted for free and the sound is already in the client. The only thing they misses is query and skill_table. You can't ask 40 Euro for them. Also you don't have my permission to do it, you thief.
I'm Italian and I got to know Ridack on youtube. These day I bought various armors, new buildings and new npc.
The price is fair enough. There are no problems. The support is always guaranteed and is very fast.
I leave you a picture.
