I'm talking in the sense of a stand-alone PC version.
While the web-version is something, I'd like to have an offline option. My internet connection at home is haphazard. There are some days where I'll have outages for hours at a time, so a single-player game that requires internet connection to play is completely unacceptable for me. If it's free-to-play or a beta test I'll accept that, but for the final release of a product I've paid for I expect it to run stand-alone on my PC.
