Left 4 Dead 2 has been popular and on-going with tons of campaigns and DLC campaigns for unlimited fun to play on both Steam and Xbox 360 but it seems that Taito has decided to go further with the arcade version of it with permissions from Valve. Perhaps, the amount of campaigns should fit in the modern arcade games that use of the service with arcade game accounts stored on the servers where you can gain access to newer content as well as to save progress but what's up with the characters in the arcade version? Not to mention that the voice acting combined with the different characters may fit in the Japanese arcades as if there won't be Asia version of those Nesica X Live games anytime soon. But the arcade version? Is that even necessary? How can an FPS game fit into the arcades like that? There was Half-Life 2 arcade version back then with HD widescreen graphics but L4D Survivor may not seem to be using up so much power of Taito Type X3 due to the fact that the graphics may seem to be same under 7th Generation console level in which the game could have been on Taito Type X2 instead. Other games that don't use Type X3's full power may include USF IV to be honest but the thing is, there won't be anymore Type X2 games that the Nesica X Live has to move on to its successor. The main reason is that Windows XP Embedded is likely to expire two years later and the arcades as we know them using PC-based hardware are likely to change as well. Maybe the older games using Windows XP Embedded will either be succeeded or abandoned.
You know, the arcade version is going to be targeted towards those who haven't played the game before on Steam or Xbox 360 but the costs for playing through every missions will be overall much larger than the consumer version price due to so much predicted hogging coming from the amount of campaigns and fun available. But better still, you may as well wait for the upcoming sequel to Half-Life 2 which will be coming in the future. Hopefully, the sequel will look next-gen-ish because the sequel coming out like that at the present isn't going to look evolved anyway.
