I played it in game club and I like it, but because of bug cannot proceed further than second or third level... I actually wonder about this game around 2010-11 and firstly found some "clearly licensed" disks on which I can't spare money anyway at that time. From that time this game popping up time to time in my memory as ghost of unfinished business and there are still no way's to legally obtain it, because my PC now not even have disc drive and cost of them is even more prohibitive than it was back then...
Look's like good enough games will stay accessible only thankfully to pirats, unfortunately. Same with Freelancer for example which still have alive and kicking community unlike this game. And frustrating part is that many objectively worse games are still available digitally because they was a cashgrabs in a first place and sold without and changes as they was released something around 20 years ago. Not all of those are bad... But still.
I personally wanted to obtain this one legally, complete walkthrough and without gamebreaking bugs to judge myself if it's oblivion deserved at least. And at least some money I ready to spend for that.
P.S.: Somehow only now I catch that it was developed by Digital Extremes which developed Warframe which I played something around 20k+ hours before game became overwhelming for me... They have good ideas in this game which You can trace in Warframe. It can be even posible that there still developers which work on this one. Mean from my view it be even easier and real to cooperate for rerelease of Pariah.
