Hello, im relatively new to rpgs in general, but i have devoured various rulebooks for games (3.5, 4e, mutants and masterminds, gurps and gurps powers, rifts, the primal order, and star wars saga edition), and am reading several more (fireborn, icons, amber diceless, hellas, nobilis, dungeons the dragoning). My play experience has thus far only been 4e the last six months, during which i subbed several times as dm in an encounters session and got good feedback.
I like optimizing characters, but i try not to overdo it, cuz it can really alienate people. As a dm, my style is rather permissive. I fudge numbers sometimes (usually in players favor), arbitrarily decide whether a monsters power recharges (if half the party is down, it doesnt recharge, for example, or if the pcs are kicking butt, it definitely recharges), and try to let creative efforts be at least partially effective. Basically, the kind of dm i woulld like to play with.
