The latter. Like, how not to lose the game with only 1 star.
Sure! Here are a few general tips I could think of. Just keep in mind that I never played the Steam version of Scythe, just the board game, but I'll assume all concepts are the same between the two versions.
- It's easy to get overwhelmed with all the possibilities and all the things you could do. The best is to choose one beneficial thing you would like to achieve at a time (e.g., do a useful upgrade, deploy a specific mech, enlist a recruit, build a structure, etc.) and work toward achieving just that thing. Focus on it. Once you could do it, choose another.
- As a general rule of thumb, try to do both the top and bottom action of a row by your 3rd or 4th turn.
- Don't fight against your player mat by insisting to do things it's not meant for. The combination of actions can be drastically different from one mat to another, and because of this it's absolutely possible that a specific strategy that was successful for you in a previous game would now be completely unfeasible. You need to adapt to your mat. At the beginning of the game, take the time to study it, and plan your game accordingly.
- Related to the above point, most of the mats have one action that can become really cheap (i.e., only 1 or 2 resources) after doing a few upgrades, as well as giving a lot of money (and sometimes other useful things like popularity or power). This action should be your bread and butter. Even when you don't have an upgrade, structure, mech, or recruit to get out of this action anymore, continue doing it often as it will easily get you a lot of money. And don't forget that money equals to victory points in this game.
- Throughout the game, keep an eye on the popularity track. You don't want to end up in a lower section of this track than your opponents. Many times it would equal to a loss, even if you have more stars, territories, and resources.
- The idea of combat can be really dissuasive in this game. You can bluff your way and make the opponents believe that you're more powerful than you really are, convincing them to leave you alone, or even retreat. If you do enter combat, make sure you're not left completely powerless afterwards. Sometimes, it's better to lose a fight on purpose than to be left with just a few power points and 0 combat card. It's easy to force some opponents to retreat after they became suddenly powerless because of a recent fight.
- For your first games, don't play with the factions coming from the expansion (Albion and Togawa) as they are a bit more difficult to play than the regular factions. Make sure you have learned the basics first. I would also advise not playing with the airship expansion at first for the same reasons.
That's what I could think of right now. I'll add more if I think of anything else. Have fun!
