It's ok if someone does not react positively to a game. But it also depends on the reason.Not unexpected. There will be people who are not disappointed as they have different views and expectations.
Take a look at the Metacritic report for ME3
Generally favorable reviews based on 23 Critic Reviews
5.9 / 10
Mixed or average reviews based on 6772 Ratings
Also of note
Q: Are user votes included in the METASCORE calculations?
It scored high with "Critic" well 23 of them that were not "disappointed"
Yet 6772 users who rated the game gave it barely above average score of 5.9
Which do you think is a better statistical sampling a score form "23" critic reviews or a 5.9 score form 6772 user ratings
There is also the fact that some look for different things in games:
- some just want "challenge" " mechanics" "action" "DPS"
- some would rather story, romance,relationship development & side quests other npc character development, companion conversations, lots of cutscenes , involvement , choices options that genuinely matter change the game path, story, interactions , environment similar more similar to an interactive movie than a " action game" ( think tabletop D&D experience)
So yes there are going to be people who react both positively and negatively.
The question remains who will be the greater proportion when the dust settles.
For the reason stated above I have a dread it may be another ME3 situation and so I am not willing to risk another disappointment and was already suffering from buyers remorse before the game was even out.
Many people (too many people) is negative to a game not because there is something objectively wrong, but because "it's not what I want".
A game is not what the player wants. A game is what the developers want the player to experience.
As for the points you wrote about in the previous message let me say a few things:
1) Third person: was never in the game. The game was created with the idea of a first person RPG. Again, a game is not what the player wants but what the devs want the players to play.
2) Romances: we know nothing yet, since everything that was revealed is from the first part of the game. And it's ok that you can't experience all the romances options in the same run. If you do that in TW3 you know what happens, let me just say (to avoid spoilers to anyone who has not played TW3 yet) that you can't have them all (in a single run).
3) Shorter game: they said it's going to be a bit shorter. We don't know how much shorter than TW3. TW3 was a long game. Very long. And this one looks like it's going to be very long too. Maybe a few hours less than TW3? It's fine. It's not "the bigger the better, the longer the better". When the final credits roll, if the player is satisfied, it doesn't matter how many hours the game was long. Plus, this time the game should have way more replay value since you can do a completely different character and replay the game differently.
But still it's ok if you're not fully convinced. You don't have to preorder and play day one. You can simply wait for reviews, extended gameplays and so on in order to understand if it's something you want to play. If not, it's ok, a game cannot satisfy everyone's personal taste.
Plus, if you're interested, a few "hands on" are now online, you can read them to better understand what the game is like.
