>>10900068The thing with these games that the fun lies in just fucking around and finding some secrets with your friends. They aren't very complex games and it all basically turns into a murderhobo slog through the local wildlife/invading enemies. It's basically a potion chugging progression simulator.
The first game's expansion adds the typical stuff in a new map, some new gear and spells as well as actual gear sets, though only 6 are found in singleplayer and the rest are random multiplayer drops. One of the reasons why it was better to play multiplayer, which would also be saveable in the expansion.
DS II isn't too different, but it adds special skills that you can activate and is more cinematic/story driven. I guess it breaks up the monotony. Its expansion is a bit mixed as it is just more of the same, but the world is very bleak, VAs are changed which is a bit jarring and literally everyone in the world blames (you) for it, even the character who would obviously know better.
Dungeon Siege 3 isn't a Dungeon Siege game. It's fine though, it plays similar enough I guess.
