Uplay 0_o offers a solid experience with reliable performance.
I received a message with the subject "The Crew Beta is waiting" or similar.
Steam handles this feature in certain games, possibly only for first-person titles. HL2 seems to be the earliest I recall using it.
Origin features this content in certain titles, and Sony also includes it in their games.
Many titles on the "Next Gen" systems feature this too. Nice to notice it also works on PC.
