What is the crowd's opinion of Serious Sam?

From 3.5 billion comments

Fallout 4 VR will arguably be the first true AAA VR game.

ED was a kickstarter game developed by fantastic indie studio Frontier. That's if you ignore the fact that ED, wonder as it is, is a game in much the same way Microsoft Flight Simulator was a game.

Star Trek: Bridge Crew is a tech demo.

Croteam themselves list Serious Sam as an indie game on their own site

Croteam - One of my personal favorite developers. Constantly updating and improving on their older games. Implementing Vulcan support etc.
