Feature points are a good idea. One circumstance that came up involved our Rookie GL trying to interface with a planet-side computer & discovering that the system had both an AI of it's own and intrusion defenses. I assumed that Oan technology was superior and allowed the GL to easily win the contest and connect with the AI in order to grab some needed info. But, in a closer contest, it might be something I would want to solve with a Die Roll.
In a case like this, should the GL have to take Ranks of power, or is this just really one Feature vs. another that is best resolved by GM fiat? Would the heroes powers and skills actually have any affect on the AI's ability to cope with alien technology?
My sense is that a base-line GL might be far more powerful than generally implied and that a Power Ring is practically a Minion in some respects (at least how they're used in the comics). And, radical differences in Technology Levels could also be critical when incorporating devices, equipment & features. A Legion of Super Heroes common communicator and computer would far out strip a Dell PC and Smart Phone. I wonder if Book 4 will touch on any of this?
Any other ideas or suggestions would be wonderful.
