2017 is increasingly looking like a year of major changes in the video game world. Twelve months ago, many industry insiders were skeptical about Nintendo's next console. And Activision's "Call of Duty" was still an unstoppable beast of a franchise. Over the last 12 months, though, "Call of Duty" has seen its sales longevity waver. Nintendo is on the upswing again. And Ubisoft has dramatically strengthened its standing in the industry. Midyear sales figures for the video game industry show two things — the staying power of hot holiday sellers and which spring releases have found a loyal audience. While the positions shift (and many titles fall off the charts) once the holiday months arrive, they're a good barometer of publisher health. Rankings for this midyear list were taken from sales figures from January through the end of April, the most recent reporting period for market researcher The NPD Group. Due to agreements with publishers, NPD does not publicly release hard sales numbers — but the rankings show that players are eager for new experiences — while they're not quite ready to let go of some old favorites.

10. MLB The Show 17

(Publisher: Sony) — Baseball games don't have quite the appeal among gamers as football and soccer titles. In fact, Sony is the only company making them these days. (Electronic Arts shuttered its "MVP Baseball" in 2005.) But the sales dominance of the PlayStation 4 has helped push "MLB 17" onto this year's list. It will certainly drop off before the end of the year, but its strong performance in the first half of the year is still notable.

9. Call of Duty: Infinite Warfare

(Publisher: Activision Blizzard) — "Infinite Warfare" was a troubled "Call of Duty" title from the moment it made its debut, with fans blasting the debut trailer for deviating too far from the franchise's roots. That reaction has seemingly impacted catalog sales. Typically, the previous year's "COD" game is at or near the top of the midyear sales list. This year it's near the bottom. Activision hopes this year's "Call of Duty: WWII" gets a warmer reaction.

8. NBA 2K17

(Publisher: Take-Two Interactive Software) — The sports world used to be the sole domain of Electronic Arts, but the 1999 launch of the first "NBA 2K" changed the game. Today, the franchise is one of Take-Two's most profitable — and has a fan base that buys each new installment regularly throughout the year. In recent months, Take-Two and the NBA have partnered on an esports league that will continue to bolster the public profile of "NBA 2K."

7. Grand Theft Auto V

(Publisher: Take-Two Interactive Software) — It is nothing less than astonishing that a nearly four-year-old game, first released before the current generation of consoles came out, is still one of the top-selling titles in the industry — even if that game is "Grand Theft Auto." It's the gift that keeps on giving for Take-Two, with life-to-date sales of more than 80 million units. The game not only has a compelling single-player element, but developer Rockstar is regularly adding multiplayer components to keep players engaged.

6. Resident Evil 7: Biohazard

(Publisher: Capcom) – The horror franchise is always a favorite among players, but the most recent version had a special appeal for PlayStation 4 owners: The entire title could be played in virtual reality through the PlayStation VR headset. That nudged some buyers who normally might not have picked up a copy, but the big draw was the game received the franchise's best review scores in 12 years.

5. Mass Effect: Andromeda

(Publisher: Electronic Arts) — "Andromeda" did not get the same critical love as "Resident Evil." In fact, many fans were disappointed with the game. But previous entries in the series carried such goodwill that it still managed to rack up impressive sales in the first half of the year. Don't look for a follow-up anytime soon, though. Electronic Arts has reportedly put subsequent sequels in the franchise on ice.

4. Horizon Zero Dawn

(Publisher: Sony) — Sony's PlayStation 4-exclusive open-world action/role-playing game had one of the best debuts of any new franchise in the company's history. Sony says the game sold 3.4 million units worldwide, virtually guaranteeing that Aloy, the hunter/archer living in a post-apocalyptic world overrun by robots, will get a sequel.

3. The Legend of Zelda: Breath of the wild

(Publisher: Nintendo) — How popular is this long-awaited open-world "Zelda" game? So popular that it outsold the console it runs on. Worldwide, the game sold 2.76 million copies of the Nintendo Switch version of the game through March 31, according to Nintendo. The Switch, in that same time period, sold 2.74 million units. Whatever the reason, the game has certainly earned the success. It's one of the most highly rated games of all time by critics. And it's so loaded with surprises and solid gameplay that it's easy to get lost in Hyrule, the game's mythical world, for 100 hours or more.

2. For Honor

(Publisher: Ubisoft) — Ubisoft lands a one-two punch at the top of the midyear sales list with this hack-and-slash fighting game that pitted Vikings against samurais against knights. While the multiplayer elements faced some criticism, fans appreciated that the game rewarded patience, rather than letting people simply mash buttons on their controller randomly and still win fights.
