Any websites you like or Youtube reviewers? I prefer reviewers who also check out obscure games and actually point out flaws.
Console gaming mostly since PC has Steam reviews that help out.
I've always used Metacritic since it aggregates reviews, but it seems to have gotten worse for searching and finding top lists lately. There's gotta be better sources nowadays.
I like patient gamer communities, since I can get a fan consensus, a lot of hype or hate has died down, and there's been some time to work out the kinks and send out updates.
