Fallout meets Jagged Alliance and Fallout:Tactics.
Back in the old days I always thought "Fallout story and interaction with NPCs is awesome, but I hate my stupid companions who either get in my SMG fire or run into melee combat with 5 deathclaws."
At the same time when playing F:Tactics I thought "I love the combat system and cool killing animations. Vehicles can move and be used in combat and with an optional CBT mode (mix of turn based and real time) I can even change tactics to supressive fire, drive by gunning, etc... It's just pity that interactions with NPC are almost non existent, without any dialogue options or side missions like in Fallout 1 and 2."
And for both games "How I wish they could combine the best elements of those games". More than 1 decade later I think my wish has been granted.
