If they're more games out there like Shenmue, can someone point me to them? I can't see any personally. Sleeping Dogs, GTA and Yakuza are definitely not the same if those are the ones people are talking about.
As stated earlier in this thread, I think if they were to carry on with the series, they'd need a reboot. Simply remastering or releasing Shenmue 1 and 2 in it's outdated state now would be a flop I suspect. That may sound expensive, but it really wouldn't be with technology now. Back then, they had to hard code all the things that come built in with most engines now.
