I just won my first Monarch game (PTW, as the English) and played the whole thing with zero research (one poorly managed scientist). On Regent I was used to trailing the AI and pulling ahead around the end of the AA. It is widely said that you can out-tech the AI on Monarch, but when/how do you make the switch from buying to studying? I made a couple abortive efforts (resulting in a handful of libraries and two or three universities) but I never could... I was always in gpt deals that wouldn't let me set research higher than 30% or so, and all my infrastructure was economic (stock exchanges everywhere, no tech improvements most places.) Does it make sense to start off buying and switch later in the game? If so, how and when do you do it?
