I’d definately go the review route of the two. But by “review” I don’t mean churn out the usual garbage about how great a place is, how amazing the games are etc etc, but do a proper review – here are the good points and the bad points, and let your visitors see that it’s objective and a trustworthy source.
Better still, try and find a niche that you know a lo about – specific types of games, experiences or maybe something more unique. Work yourself up as an authority. That’s where the long term success in this industry lies IMO.
