If they make the exploration meaningful and fun (i.e., not like DA:I), I could see this being pretty cool -- playing as an explorer, looking for a new home for humanity, it's basically an RPG version of Interstellar. I'm increasingly skeptical of Bioware's ability to tell a coherent and engaging story, but maybe this would be a reasonable and flexible framework for a less focused but still enjoyable affair.
They've talked up going to Andromeda as an opportunity to thematically highlight this frontier aspect of space exploration.That's neat, but the environments shown all look so familiar. If I'm going to spend hours driving around in the Mako, I want it to be through what feel likely truly alien worlds, not just "desert world" "jungle world" "ice world" etc.
I can accept making each planet only one biome just for the sake of practicality. But, so far, the planets they've shown look really bleh. Like just Earth biomes and geology w/ a few aliens flying/running around. Some nice sky boxes mind, but still disappointing. Not sure if this is a failure of imagination from Bioware's environment artists, limitations of the engine/development, or they just haven't shown the more interesting planets.
