Two more free to play weekend for two very highly rated games.
Borderlands is until 24 April 3:00am.
Northgard is until 21 April 3:00am.
Normally there will be offers for these games going along with these weekends.
Botderlands is also in the current 2K Humble Bundle along with an XCOM and the Bioshock games - that might be an option if you like the game enough to buy.
Enjoy.
There must be only 6 people left on Earth who don't own Borderlands yet. I think it's been in about 3000 bundles over the years, it's been free/included in subscription on a bunch of consoles or it's been so cheap that everyone has bought it.
Oh to be those 6 people though. It's great for when you finally get it.
