Hello,
If i claim a game, if that free forever, so long as i have Pro?
If i claim a game, and its removed from the list after a couple of weeks, will this still remain playable?
Yep, once you claim a "Pro" game it's yours to play for as long as you have a pro subscription. You can even cancel Pro, let it lapse, re-join, and you can have access to those previously claimed games.

If a claimed game gets "off the pro list" you can still play it after it's removed. For example I can still play, "Kona" but it's currently not up for grabs in Pro.
