There are some research tracks where it makes sense to just take one or two steps, and others which are only worth it if you go all-in to grab level 5.All-in tracks are:
- Terraforming
- Economy
- Science
Navigation level 2 is often sufficient (though the Lost Planet from level 5 is definitely worth it). Advancing on Artificial Intelligence pays off more the higher you get, but it's also ok if you just do it to get the assigned tech tile and a QIC. Gaia Project research level 2 may also be sufficient to grab some conveniently placed Transdim planet one per round - of course if you're Terrans, you want level 5 and its warm rain of VP. :)
