I have always been in favour of the incremental research system whereby each Power begins the game at some point along a ‘ladder’ in achieving a given tech. When they reach the end of that ladder, they have achieved the tech. Each tech lader would be say, 10 points (or steps) long and it would cost 5 IPCs to move your Power’s control marker one step further - but perhaps you could only attain one point per tech, per turn.
So for example, Germany may be at 7 or 8 towards Super Submarines, and maybe 6 towards Rockets, but only 3 for Heavy Bombers. And this would be based on the historical situation.
I’m sure this system has been proposed before by people but I think it needs to be raised, now and again, as a possible house rule.
