I plan on different races for specific romances. Since 8 romances and 8 race/sex in total, I matched them and made 8 inquisitors so to try out.
And for different world state, different choices. I mean, I really want to meet Warden Loghain.
Also for aSSQUISITOr play through of course, it feels great to be rude to anyone, and try out every companions' low approval scene. Never need to care about their approval when making decisions anymore.
The more play through I tried, most of my original views towards the game overall as well as all those companions, quests, lore, etc have changed. Maybe because different inquisitors provide different perspectives. I hated Sera on my first playthrough but I started find her lovely in my qunari playthrough. So.
