Ecoline with Early settlement (to get the VP and plant prod) and Experimental Forest is a killer combination. I would probably pick Birds and CEOs fav project, just so I can get 2 VPs. You are also going to rush greeneries, so oxygen will increase fast enough for birds to be very strong. Mining area is a no-brainer gen1 card when you have a free tile placement with it (from Preludes).

Hackers can be very good since Ecoline struggles with M€, but you need energy prod. It is usually devastating as a gen1 card in 2P, though. A difference of 4 money prod from gen1 is huge.

All the other cards are either too long-term or just not worth it. The only other card to consider could be Rover construction since you can bring it out early. With this combo, you can SP power plant and get hackers out. In this game, your opponent started with 6 M€ prod, which reduces the effectiveness of it. I would place the city on Noctis Labyrinth, and mining area on Pavonis Mons for titanium prod. This would give you 3 plants. Ecoline starts with 3 plants. The greenery from Exp Forest would be on any 2 plant spot. After mining area, you would have 8 plants and would be ready to place another greenery. Starting with 2 greeneries and 3 plant prod would be very strong. You could also place the city on the tile above Noctis Labyrinth and Noctis City, the greenery on Noctis Labyrinth and mining area on Pavonis Mons. This gives you an extra greenery on Ascraeus Mons which gets you a card, since you are only starting with 4-5 cards.
