Here are his reasons why MMORPGs die and my experience related to MWO:
1. Time Investment and over abundance of MMO games.
Currently I play four different F2P MMO games in addition to MWO. Team Fortress 2, League of Legends, Hearthstone, and Heroes of the Storm. And I just bought Killing Floor 2. So my time is already divided between progression and dailies of those games. Not to mention I got a lot of buddies playing LoL. So unless there is an event going on that is non-CW, I simply do not play MWO for extended period of time.
2. Over-hype and under deliver.
I think all Closed Beta players; especially the Founders can relate to this. When MWO and the features it was to contain upon release was first announced we ****** our pants. We talked about it excitedly with our family members, with our friends--especially the guys we played previous MW games with, and there was huge buzz in general.
When we finally got into the game, the experience was great. We got the familiar stompy mech shooter we wanted. Sure there were bugs and balancing issues but the graphics were awesome back in the day, and the community had deeply cared about the game because we held hope that all the features yet to deliver was to come sooner than later.
Which was why it had hurt when PGI had announced that MWO release would be simply a line in the sand, instead of arriving with the CW we had feverishly wished for. Nearly 2 years of development time with very little progress to show for had alienated a lot of the old guard. One might say PGI was simply learning to walk before it can run, but the damage was done. And when CW had finally arrived, most players gotten tired of it pretty quickly, with only 15% still play it.
My wish is that PGI would do better in the Steam release and really WOW the influx of the new players. Cause almost all of them would not play it for the lore or care about it.
3. Bugs, Exploits, and Hackers.
I think MWO is pretty clean in such aspects. I'm sure there are people whole use cheats but those are never numerous enough to cause serious issues. Can't say the same once the game hits Steam though. Better get some anti-cheat software, heh.
4. Free to play, and pay to win.
MWO is a micro-transaction based F2P MMO game--except the transactions are not really "micro" at all. A single decent color costs $5. A single regular and Hero mechs cost anywhere from $15-45, and Packs--while offering value for the price--cost from $20-120. I buy whole games, for less.
That said, there is almost no P2W issue in MWO. Sure, the Hero mechs are locked for MC only but they are more of a "Pay to play different" than being flat out OP, except the old Ember and Dragon Slayer.

However, the gating in MWO by mechbay is real. Without mechbay, there is simply no incentive to grind for new mechs since selling the old one is a stupid idea. There are events that offer mechbays but those are far from enough. Again, when the game hits Steam, a lot of new players will be grinding for new mechs and they will be turned off by the four free mechbay limit.
5. Oversaturation.
MWO is safe in this regards, since there is no game quite like this. Sure there are mech games in the market such as Hawken, and the newcomer Heavy Gear, but they play very differently.
6. Losing touch with the community.
I could make a "You are on an Island" joke here, except it wouldn't be funny. Cause that **** wasn't funny in the first place. Pre-IGP split PGI was notorious for not listening to the community and doing something totally opposite of the community's desires. The communication had seemed to improve from the later half of 2014... ...but it certainly had affected a lot of players' decision to spend more money on the game. I know I am still holding my wallet shut due to some old unresolved grudges.
7. Lack of Creativity.
PGI is a mixed bag on this topic. On one hand, the mechs, weapons, and maps were designed with much creativity. On the other hand, overall balancing, skill trees, game modes, and lack of certain immersive aspects just scream "lazy".
8. Poor launch expereince.
As I said above, PGI had better WOW the Steam horde, cause their reviews are merciless. Stuff like limited mechbays, high content price, and the C-Bill grind will certainly be noticed. Steam players got buttloads of other games they can play for free or cheaply, so if they leave, they probabaly aint coming back. And server issues will be another demon waiting to be unleashed. We already have hit-reg issues with the current limited player base. IMO, certain weapons need to be redesigned to limit their vulnerability hit-reg issues. Especially missiles and PPCs.
9. Lack of content; especially end game content.
In terms of mechs, MWO has plenty to grind for. In terms of endgame content, PGI has what? Community Warfare? Modules? Skill trees unlocks? If so, those are pretty poorly implemented as of right now. Not enough to keep many poeple interested, IMO.
10. World of Warcraft.
I still play WoW in a free server, personally (WotLK expansion, cause the later ones are crap). So it certainly takes away the the time I could be spending on MWO. Still, many issues I listed above have more to do with the fact why MWO is no longer the magnet it used to be for me.
Anyway, jaw away.
