I've heard...not good things about the 2d20 system. Anyone care to give the two sentence synopsis of why? I'd love for my group to be able punch some Nazis...maybe even back them into the random propeller (airplane, or boat, I'm not picky).
I'll be contrary to the bad press. I love the 2D20 system, though I won't call myself a fanboy.
Not all variants have been great. Some are too crunchy for their own good (
Conan was like that and I didn't much care for
Fallout, either) and there are variants that I've felt are too abstract.
My favorite iteration of it is
Star Trek Adventures, where characters have six attributes, six disciplines (skills), some talents (special abilities), and some focuses (basically situational specializations). What 2D20 really does a great job of is getting the PCs to work as a team and to push their luck. People beef about the Momentum/Threat metacurrency but I've also found that given some experience with the system and nice description by the players and GM, it slides into the background pretty fast. In
STA, characters can have the exact same attributes and disciplines and end up feeling very different due to their talents and focuses, so PCs really do get differentiated. You can build a character that rocks a certain task or one that is great at helping others do what they need. I'm currently playing the Captain in our game; this feels very different than being in other roles. I don't do too much primary actions myself but I'm constantly helping others get the most out of their characters.
One really big tip for making a 2D20 game fun is to think of the action loop as involving characters who are active against the problem at hand (combat, out of combat). The rest are there supporting by getting rid of negative traits (disadvantages), helping, creating positive traits (advantages), or generating Momentum. Definitely don't just roll 2D20 and hope to succeed... you should always be stacking the deck in your favor.
Is it the be-all? No, of course not. It's really good at pulpy kinds of games like
Achtung! Chthulhu or
STA. It does a great job of emulating the vibe of a TV show or a lower powered action movie, and it does a great job of encouraging the "ensemble cast" feeling that TTRPGs need. I'd not want to play it all the time but I could see it work for a pulp type property such as
Wolfenstein.
