Rise/Sunbreak is no small game. The World game was the first built from the spin-off team, but you're right that Rise/Sunbreak is from the "Portable" team. I love World dearly for so many reasons, but honestly Rise keeps the old school spirit going that World was a little lacking in. The flare shot or friends only multiplayer system (lack of lobbies list) sort of stiffles the community. This might sound lame to some people, but if you've ever made long term friends with strangers you met playing a game, you're about 10x more likely to do that in Rise than in World imo. It's just funner and more often has a sillier vibe when grouping up with others, and easier to regroup with them on play sessions days later.
