Every game dies down eventually, it's natural. But i'm sure this game will be quite alive for some time

Basing my reasoning off the beta I am going to say no. The beta had me and many others addicted. Titanfall didn't have that feel. Only time will tell, but I believe that it will not die any time soon after release.

I highly doubt it dying. Being Bungie's first huge market game in a while.
They are going to be putting a bunch of support into it and people are going to be playing the hell out if it. As am I.

I'm going to say no. A lot of people have been waiting for this game for a while and it'll probably be amazing!

Destiny is hyped up much more! I hope it doesn't die

titanfall was like many other fps games we have seen but you could get in titans and jump high not that good is it really, but destiny you can use magic which is beast it's open world (multiplayer and story) which is an awesome thing i reckon the community will be strong and long lasting plus it's like some really popular games reminds me of halo(design and multiplayer),borderlands(levelled items legendary etc) and skyrim(open world) in one

Titanfall died very quickly in the first 5 weeks after It's release and I heard It's pretty repetitive. Destiny might be like but at the same time I'd rather have fun in the game then think It will be repetitive, there will be an new things happening frequently in the game as Bungie hyped it up in the beta. There are times where I think the game isn't all that amazing, but I think this will be a big hit.

Bungie has been known for producing high quality games; example being the Halo Series.

I know they have put more than enough effort for this to be a top quality game for everyone to have fun off of. As long as they supply
updates to the game, it will live for quite a while.

Irregardless I'm excited for it, and I'm going to play it, it's just in Bungie's hands to maintain it.

Truly I will say this every game dies out.
For example when you get the game your like man ill play this game forever
a few months later man this game is so boring now its normal to feel that way.
