I'm an experienced player that has been playing for more than ten years. Played a lot of games but those I played the most are Mekton Z, Vampire: The Masquerade, Warhammer Fantasy, Anima: Beyond Fantasy and LOTR(The old one).
I alternate between playing and being GM, and my favorite game would be Anima:BF, having directed as GM a couple of campaigns and played for years I'm used to complicated systems.
Both as player and GM I like to play in "Hard" mode; In our usual game group character deaths are normal and some campaigns have ended because the whole group was wiped, so you have been warned ^^.
