First time playing through the Geneforge series and I'm liking what I've played of it so far. I've just finished Geneforge 3 and will be looking to move onto Geneforge 4 soon. I've been trying to keep my faction choices as close to what seems to be the "canon" route as possible, and yes I'm aware that the endings don't always tie in perfectly with the subsequent but so far it's been close enough. My choices so far have been:
G1 - Pro Shaper, killed trajkov & goettsch, sided with Obeyers, didn't use the Geneforge.
G2 - Powergamed, sided with most factions in turn then wiped the lot out and reported back to the shapers for a pro-shaper ending.
G3 - Mostly pro-rebel, started out pro-shaper and transitioned across to the rebel side as that's where the plot seemed to want me to go and it felt like a natural progression. Litalia flipped out at the end, mistaking me for a shaper loyalist (a bug, presumably from glancing at the scripts) and attacked me in the geneforge but for continuity reasons I'll pretend that didn't happen. Killed Rahul and sailed away with Akhari Blaze's blessing.
Now I'm probably going to play through the Avernum remake next to give myself a bit of a break from the Geneforge series, however when I return, which path/faction in Geneforge 4 leads most "cleanly" into Geneforge 5 with the fewest plot contradictions? I did read a suggested set of faction choices for each game on this very board a while back but can't find it for the life of me now...
