If you like Assassins game after playing the ones that you mentioned then you'll like these games as well. Nothing very good nothing very bad. Average games as they started coming every year. Origins is very good and huge improvement as per reviews and all. Personally I haven't played that game.Ok so here is the list to be played:
1. AC
2. AC2
3. AC3 (can be skipped)
4. AC Brotherhood
5. AC Revelations
6. AC4 - Pirates
and what about :
1. Assassin's Creed: Freedom Cry
2. Assassin's Creed Rogue
3. Assassin's Creed Unity
4. Assassin's Creed Chronicles: China
5. Assassin's Creed Syndicate
6. Assassin's Creed Chronicles: India
7. Assassin's Creed Chronicles: Russia
and the latest Assassin's Creed Origins
ACS & ACO are optimized well for PC (except for high CPU usage due to Denuvo in ACO). AC Unity tried to push graphics beyond the hardware capability of the time, together with not so good optimisation, it lagged.AC: Unity with unplayable lags ruined the AC experience for me.
Whether AC:S and AC:O are optimized for PC ?
TrueEven unity has been optimized with many patches and is now in very much playable state.
So, playing AC Origins for more than two months and now I can say with confidence: this is a great and very interesting game in the series. Beautiful graphics and gameplay. Also I think that there are many similarities between AC Origins and The Witcher. For example, combat system and landscapes. Anyway, it is a cool game. But the cons are the large amount of purchased content and... the camel with a rainbow on a hump
