I don't think there's anything inherently wrong with that, just as there's nothing wrong with a Kickstarter remaking a CoD style game (and no, there'd be no lawsuits unless it was an actual CoD game, they can't go for them for having a modern warfare themed FPS). If it's something that people enjoy, then why not make it? I wanted to see a new XCOM, so I paid for Xenonauts (didn't Kickstart though, one payment is enough). There are lots of old games that I'd like to see a sequel to, or old mechanics I'd like to see resurrected. I can't 100% follow the RPG argument going on and I've never played cRPGs, but I like some of the mechanics that people are describing.
But that's not innovative and Kickstarter effectively won't drive gaming forward as some have suggested if all devs do is remake things from the 90s. It's just another iteration of what came before. Not everything needs to be innovative, which is good because some of the best games aren't innovative and some that innovate do a poor job of it and are crappy games, but the original article's point still stands. Kickstarter has always been about making a game that will make money when all is said and done, and nostalgia sells lately on the PC. But it's by no means innovation to bring back a dead gameplay mechanic.
