I am both eager as well as concerned about ME4 and as such would not be buying it at launch
- eager , because Bioware is still (largely) Bioware and knows how to tell the story like few else.
- concern, well, EA is still EA and does a lot of things I greatly don't like
-- I don't like turning amazing RPG stories into stupid (sorry, accessible) shooters.
-- I don't like forced MP, really? if you want to blast things online there are tons of games for you, with great physics , teams, etc. all of the battlefields, titanfalls, etc. please leave RPGs alone
-- I hate forced link between MP and SP , I think it was called 'galactic readiness' or something stupid as that. I want a great SP experience, at my pace , in a world that could suck you in and engage you, make you care about characters, about their choices, your choices, etc. Not constant nerphing and updates, and rebalances, because companies try to turn everything into online sport.
-- don't like DLC to death crap.
So I will be playing Kingdom Come Deliverance earlier in the year and see what comes out of ME4 (with patches, updates ,etc) by the summer..
