"Over the last 8 years, you've spent 3340.6 hours playing this selection, which includes 70 items, is valued at $975.4, and requires 365.9 GB"
Would be more hours but I've deleted my TF2 stats like twice.
Also CoD: BO was played by my brother.
Have some games I got in a deal that I haven't touched tho, others I don't remember buying.
