I believe that some running simulators are basically too plain and simple, let's take Run 3 unblocked for example. Why not add some bonuses for successfully passing the certain levels or boosters to increase or decrease the speed of movement? It would be really nice.
I can advise usacasinoville.com site, here you can find an article about interesting games, however, it will help if you are interested in gambling. Personally, this site seemed to me the most informative of those that I met. If you like it, great, if not, then in any case you will find a lot of interesting facts about games.
