INTRODUCTION & GAME STATUS
Because February was such a hectic month with three entries, I wanted to lower the pace and focus on just one big entry for a properly classic game this month. Actually, work on the comparison of Trailblazer started late last year already, but was postponed due to finding out about two relatively new unofficial conversions, one for a machine I had never even heard about before - Tesla PMD 85. Well, now is the time, and here's to hoping this classic ball-rolling game gets the comparison it deserves.
