> That is why the next leap ahead in games was not Quake 2 (1997), but Half Life (1998) which was, tellingly, based on the older tech Quake 1 engine How is that telling? Source is based on Q1 instead of Q2 because Valve decided to keep working on the HL1 engine (GoldSrc) which already had extensive modifications from Q1 instead of rebasing all that work on Q2 or another engine. It's a perfectly valid decision irrespective of the quality of the Q2 engine.
