Heh ! I actually tried to play dragon age but quit relatively early in the playthrough. Thanks for mentioning it.
I guess it's time to reinstall this game.
The 3 are good.
The 2nd one has a good story but was rushed and poorly made. Worth playing nonetheless i think. 1 and 3 are must play.
Make sure to install all the DLC and Add-on, they add characters and stuff to do. The golem in the 1st one is hilarious...
And play all the intro in the 1st one, since they all are different, they give you lore, and then when you arrive at "ostergar" if memory serve, choose which one will be your hero.
Leliana and the elf can be bisexual the other npc are heteros. There's several romantic and kinky moments, and as other mentioned a few possible 3somes.
All the games are a long run, takes scores of hours to do them.
Make sure to talk to your companion and NPC. Unlike any other game I played they have things to say, and will add new stuff over time as the stories goes and they begin to open to you. They also like or dislike each other, and will chat and banter quite a lot, sometimes you be pissed because you get attacked and thus there conversation get interrupted.
It's a pleasure to listen and talk to them whereas in other games you need to turn the sound off or to download stuff to make them shut-up!
But, keep in mind, but for alistair whom even if you make him hate you will be by your side all the others, could leave you, turn on you or betray you. They've personalities.
And save a lot, remember that it's one of the rare adult game. Very little kinky stuffs, since you need to build relationship, and are stuck battling etc. But enemies are not stupid, they don't oblige you by dying easily, there's tons of lore, and the enemies have a reason to behave the way they do, they think that they're the heroes! and have the right to behave as they do... And your choices matter, if you ally with a faction the other will not like it...
