It ends tomorrow (20.06 at 18:00 GMT/10am PST) which is a shame so any lingering demos anyone wants to try, download them ASAP because most will get removed when the event is over.
I tried about 13 games in the end - here's a few picks from what I remember:-
Gloomwood - a spiritual successor to the first two Thief games.
Trepang2 - awful name but as close to F.E.A.R as we'll likely ever get. Needs some fine tuning but otherwise it looks fantastic!
Metal: Hellsinger - really well made game. Not quite as fluid as I would've hoped but the soundtrack is awesome and the visuals look really good
Some others:-
Agent 64: Spies Never Die - A love letter to Goldeneye but not quite there. Has its moments but the UI is bland, the visuals look a bit washed and the mechanics aren't as authentic as I would've hoped.
Cult of the Lamb - interesting rogue-lite with a unique style but the controls need desperate rebinding and I'm not entirely sold on the gameplay depth.
Old Skies - big fan of WadjetEye games and their range of point and click titles. This one is a step up visually but the gameplay feels slow and I wasn't terrible intrigued by it all.
Alaskan Truck Simulator - very disappointing in most departments. It was never going to touch SCS's range of simulators but this one misses the mark on almost everything.
