RCT2 and the original RCT are all-time classic games, and RCT2 is only further enhanced by the now-stellar reimplementation OpenRCT2, which, among other things, has reimplemented the game's park save format to drastically raise object limits and allow for much greater control over the look of your parks. Both games still have large and active communities to this day.
I was fortunate enough the be able to nab the Steam version before Atari pulled it from the storefront. Besides all the bugs, which are typical of Obsidian games anyway, it's a brilliantly well-done game. One of my only complaints is the difference in how the toolset works between NWN and this game -- it seems to reserve a certain amount of space in exterior areas for background work, which is fine, but coming from NWN, it makes it a bit odd not being able to have the whole area walkable as was possible in the first game. Other than that, great job Obsidian, and great job GOG for securing not only the Platinum version, which is what Steam had, but the full gamut. MoW is very hard ti find these days!
