I bought and played Pandemic yesterday, but this post isn't really about Pandemic. It's about the bought and played yesterday. I did both. On the same day. The other player and I both read the rules. During play we made one small mistake. We still had a blast (and won't make the mistake next time).
I have never done this with an RPG. I have downloaded and played on the same day free games online, but commercial games? Never.
Imagine how many fewer games would sit unplayed on my shelf if they were at least some like Pandemic.
