Selling Well:
COD:BO3 - Campaign with a Full Realized Story. Huge Multiplayer. Zombies Mode. Theatre, Stat Tracking, Bots. That's a full release.
Fallout4: I have no idea never played it but everyone that plays it is impressed, it's massive, fans get what they hope for.
Selling Poorly:
Star Wars Battlefront: This is basically a $20 Star Wars themed DLC EA is trying to rip off for $60. And people aren't falling for it. I bought this game even though I usually avoid EA and can say after about 4 hours there is no content in this game at all. Not only that but it doesn't have any connection, likeness, resemblance, characters or elements from the New Star Wars Movie that is coming out in 2 weeks. Typical EA Bullsht here.
Halo5: Halo is my main game series. 343 has driven the franchise in to the ground, they've tried to implement every single mechanic from every other FPS on the market, now they want to add Microtransactions. They cut out social playlists, some of the most popular gametypes like king of the hill and oddball. They took out staples of the Halo series like Forge and Firefight. The graphics are sht, the maps are sht. This company screwed everyone with Halo1Anniversary, Halo4, Halo:MCC, and no one was going in for another round in H5.
Tomb Raider: I assume this isn't selling well because these Indiana Jones games don't typically have amazing sales, people are only going to shell out so much for 8 hours of gameplay. Last game like this I truly loved was Prince of Persia: Sands of Time. That's one of my all time favorites but I don't put too much money into the genre. I mean there's 80 hour RPGs, Expansive Open World games like GTA, and FPS Multiplayer games with incredible playability. Most people aren't putting too much money into 8 hour campaigns alone. Although people expect a good campaign and story in their game regardless of genre. I appreciate games like this that are story, atmosphere driven but they usually don't hit it out of the park saleswise.
Gamestop: It's EA and 343/Microsoft Bullshtn their sales, Battlefront and Halo5 aren't selling well because Video Game consumers have choices, and their choosing not to buy them. I believe Gamestop is accurate when they say game sales right now are 75-80% retail and 20-25% digital. As far as digital goes, I buy all my games digitally and don't understand why someone would buy retail, until I bought Battlefront and really feel like getting rid of it. Nonetheless I'm sure by the end of this generation the Digital/Retail balance will reverse and Digital will occupy more like 60% of sales I'm assuming.
