I played the latest version and explored most of the available content. It's quality stuff, and replaying the earlier parts is still fun. This is currently my favorite project around here... But there's a big caveat to all that goodness.
The free-roaming around the hotel, police station, cybercorp, downtown, etc. sucks major ass. It really does. The exploration system works well for a first go at an area, say a mission or discovering some new place. But subsequent visits are aggravating to the extreme.You have to click through an absurd amount of screens to, say, visit Dr Lucius daily.
Please, please include a shortcut menu to access every friendly NPC/store or recurring tasks at the start of every area.
