OTOH how do you pick a game to play from a list of multiple games with no rating no review etc?
Quality of game description and topics of interest.
There is no such thing as an indie genre. But what many games have in common is that they cater to a rather narrow subgroup of any topic. Like, things not considered mainstream. Stuff that the big studios do not bother or do not like to develop.
In other words, since I already have those multiple games in my watch list, I will probably try them all or at least look very closely at the screenshots and try to guess if I would like it, based on description and tags and maybe comments.
As it was said, ratings are basically meaningless. If people do not like a thing, they do not rate at all. And some do not even rate the stuff they do like. So to be more precise, the rating average is to be taken with a grain of salt. The number of ratings is not. A game that managed to get 200 ratings and have an average of 2.0 ... how could that happen? Or even 3.0. And anything with less than 10 ratings is probably rated by the dev's brother and his mom or by the odd hater on any game topic or the dev. AI games get this hard.
