Hardrada: That is tempting. What are Big Fish Games like - any issues such as DRM or limited downloads?
There is DRM on some games published on BFG from early 2011 on. It appears that some kind of hardware signature is generated at install time. If the program is moved, it won't function because it claims that the 'hardware key' has changed.
Obviously, as long as you can access your BFG account, you can re-link each game back into your client. The client is a bit dumb (actually it calls itself the client-stub-installer), it only downloads what each installer stub tells it to fetch. So, if you change computers, you'll likely have to re-download everything to keep your SO/kids/what-have-you happy (if they use the BFG client anyway). If there's a way to back this up from the client, then I missed it.
