As someone who doesn't usually stick with one game for very long, I like seeing my playtime number hit milestones for the games I do play a lot of. It's nice to see that I've actually put a lot of hours into a game for a change.
2018 is a pretty bad time to be releasing an indie game on Steam in general. There is so much stuff coming out, great games get crowded out whenever they are released. These days to have a successful Steam game you either need to get very very lucky, or have fantastic marketing outside of Steam. Simply sticking it up on the Steam store isn't guaranteed to get your game noticed anymore, whether you do that during a Steam sale or not.
In fact, launching during the sale might lead to more exposure - not a lot of indie games are being released on PC because they're trying to avoid clashing with the sale, therefore it is probably getting more coverage in the media because there isn't much else for it to clash with. For example, if there were a ton of other games coming out right now, might it have been overlooked on Giant Bomb and not been given a Quick Look? Possibly.
@a2000: Those are both "Concept" pages, not game pages.
@twitchnmnr: Stream Avatars is not a game and the page has been deleted.
Can someone explain exactly what Marbles on Stream is and how you play it? If it is an actual interactive game that you play, it may be entitled to a page. I thought it was just a visualisation where you watch marbles fall, but if there is actual gameplay, it may be different. If the entire interactivity is you naming a marble then it randomly falls, then I'd say that's still just a visualisation, not a game.
I don't have an answer to your question. I suspect it is probably a coincidence, but hell if I know. But thank you for introducing me to the world of PC Accelerator. This magazine is something else. It's hilarious.
