I feel like this could be a good topic for the writers to keep an eye on, there are a lot of systems out there, and they all play differently. What aspects of other systems do you feel would work well with the Stargate setting, and on the flip side, is there anything that you would say wouldn’t work that well?
Star Trek Adventures
One of the reasons that STA spoke to me as a potential system to Deakin for Stargate was the simplicity of its attributes and disciplines. Rather than having a great big skill list leading to very specialised characters, STA took the alternative approach of saying that these characters are all pretty highly trained, and as such, are pretty good at everything, whilst excelling in their specialties. As such, every dice roll is based off one of six attributes (Control, daring and so on) and one of six disciplines (Command, Conn etc) whilst having a relevant focus allowed a greater critical range for additional successes. I feel that Stargate could benefit from something of a hybrid between this style and a more traditional skill based system, as some areas would require more specialisation, for instance the sciences and archaeology, etc. Whilst in areas such as combat, you would expect the characters to all have at least been through boot camp, and therefore be able to aim and hit a target. Having a greater critical range due to focusing on a specific type of weapon. Could make sense however, someone who has practiced with assault rifles or SMGs for hundreds of hours is going to be far more accurate with those weapons, and better able to inflict more damage with them, whilst not being able to handle a sniper rifle or a staff weapon with anywhere near as much efficiency.
From a sciences type of standpoint, a more traditional skill system may work better, to give areas of specialisation that characters know more about, and are therefore more likely to be able to interpret something successfully, rather than having a greater chance of understanding every single piece of this completely alien device in five seconds (crit).
I hope that all makes sense, and apologies for the mass text wall, more to come!
Modiphius’ 2D20 System
Threat is a wonderful idea, and is handled particularly well in STA in my mind, specifically when it comes to escalation.
Threat is a GM resource, that can be increased by environmental factors, situations, the result of PC actions, and most thematically for the setting, obtaining certain types of equipment and shooting to kill. In STA this manifests in reinforcing Starfleet’s ideals of trying to find the path of least destruction/violence. Whilst this isn’t as relevant to Stargate, the idea of escalation based on the players actions and equipment choices would feel applicable to me, and whilst this could be GMd pretty easily, having it in system could help with the feel of the setting.
Once again, apologies for the giant wall of text!
