I have two big issues with multiplayer in a single player game.
Number 1: I know how quickly "optional" mp can become mandatory. Just like in ME3 where to get the best possible ending you had to participate in the MP... Yes that makes in mandatory in my books.
Number 2: Mechanics for combat get balanced around mp. This is why I believe there's so many less spells in DAI, and why were limited to a small action bar.
You're ruining my game with this mp garbage. Do the Elderscrolls or Witcher series need gimmicks to sell games? No. Make a quality product and you'll sell games.
This.
1. I know they are saying over and over again basically 'hey it really is 100% optional this time, no impact on SP experience whatsoever', and I would hope this is 100% true. However, we were told when ME3 MP was announced as well that it was entirely optional. Mistake/bug as claimed or not, it is difficult for me to see past that. It's like when a significant other is discovered to have cheated on you - trust can take a long time to rebuild, it's not just automatically restored on the next date.
2. They have stated that combat balance testing was done in mp, and numerous threads exist discussing how much influence this has had on the major combat changes we have seen - no healing, limited action bar, no weapon swap, etc.
My introduction to Bioware was the brilliant, single-player stories of DAO, ME1 and ME2, and this trend of MP being added on has me worried. If Bioware or EA wants to have online, multiplayer experiences in the core IPs, I don't see why it can't be its own thing entirely - a la ESO, FF11/14, etc, while the single-player franchises I have grown to love remain just that - single-player franchises.
I still have my preorder. I am still planning to play through the full game. I will try the mp, which I actually did come to enjoy playing in ME3 (though that still does not excuse the EMS threshold fiasco). If the single-player story is as brilliant as the games that brought me to Bioware in the first place, and the MP really is completely and entirely optional with no influence on SP content whatsoever (and remains so), and the combat changes end up not really detracting from my enjoyment of SP, and the MP itself is fun, then, bravo, trust restored. If one or more of these areas fall short, I'll probably give CDPR another shot (never finished TW1 because I hated the combat), or shift my budget towards kickstarter crpgs.
