After reading some threads on this board I can see that some people are opposed to the idea of technological research, others dislike the randomness of it. However when I first got A&A Pacific 1940 I was dissapointed to find that there was no technological research. I also enjoy the randomness of it because it may cause players to adapt their strategies based on the advantages they have available, instead of always going for the exact same technology and playing the exact same way.
To the end of reintroducing what I find to be a very enjoyable aspect of the game I have created the following house rules for technology. My guiding principles were a) Is this historically plausible and realistic, b) does it add value and enjoyment to the game, and c) is it balanced and useful in comparison with the technologies originally included in the game. However they have not been thoroughly play-tested, so please feel free to give me your input, suggestions, or most especially play-testing results if you chose to use these rules.
Thanks, and happy strategizing.
