Since there seem to be a good amount of Halo players here I might as well ask for opinions, and it's kind of E3 related too.
Years ago I tried Halo 3 and, long story short, found it boring and traded it in without completing it. However I got access to the Destiny Alpha build, really like it and with a lot of people saying it is "Halo gameplay with a Borderlands world" I've started wondering:
If I ever get an X1, should I give the Halo franchise a second chance and buy the Master Chief collection?
The Master Chief Collection is four games for the price of one. Even if you end up not liking a single Halo title, you still only paid for one, so its not a huge loss of like $240+ if you bought the games as they released. Only $59.99.
I'd say give it another go, from Halo:Combat Evolved all the way through the series. You might enjoy it. If you don't, that sucks, but at least you can say you tried and it wasn't your cup of tea.
I'd say its more fun with friends playing multiplayer or playing the campaign co-op, so if you join me and several others on X1, you won't be short on company.
