Pro Pay what you want
Cubic Bundles are pay what you want for the first tier of games, which is pretty cheap and a good way to add to ones collection.
Con Bundles are not that often
Bundles can last for a month or more, with o new bundles on the horizon. Even then bundles seem to mainly be seasonal with a few thrown in between. This means it may not be the best choice for those looking to get new games daily or weekly.
