KneeTheCap: Hey, that's actually a nice rule! Can I steal that for my own giveaways?
alexkoti: Of course! I had thought to use this rule to create a giveaway, but I never ended up doing it :P
It's an interesting rule for a giveaway but I believe entry numbers would be very slim if any.
Even gamers that only redeem games they're interested in (like myself) can't find the time to play all the games they have. Especially if you're a completionist type (again like myself :)) or an achievement hunter.
Even though I don't believe it would be a successful giveaway I would like to see it for it experimental nature. :)
