Pokemon Game Japan Release
Pokemon Conquest
Platform: DS

Developed by: Koei
Published by: Nintendo
Release date: June 18th (NA), June 21(Aus), Already released(JPN)
Genre: Turn Based
A turn based game which is most likely going to cause a flood on forums just like the above game will. It has gotten some good reviews and is looking like one of the last if not last great DS release. It does have a gimmick but it plays well with the game and doesn't try to be to complex. It isn't the longest Pokemon game clocking in at 7+ hours to beat but to complete it should take much longer.
The Amazing Spider-Man
Platform: X360 PS3 WII DS PC

Developed by: Beenox
Published by: Activision
Release date: June 26th (NA), June 27(Aus), June 29(Eur)
Genre: Action/Adventure
The 3ds and Wii version do not have free roam and may be terrible. Plus Beenox ruined the latest Spider-Man DS game making me question it even more. If you must get a version go for the PS3/360/PC Version. I'm hoping it has good gameplay like some of the previous games and improves were the last one seemed to have only failed somewhat.

Gravity Rush
Platform: Vita

Developed by: SCEI
Published by: SCEA
Release date: June 12th (NA), June 13(Aus), Already released(JPN) June 14(Eur)
Genre: Platformer sort of
A 3d game where you can manipulate gravity to a certain degree It already has some poor review scores but not a game to be missed by vita players.
Hell Malice I honestly thought it said 2d sorry but I did say some poor review scores. It has some high praise from most but some hate it.
Lollipop Chainsaw
Platform: X-Box 360, PS3

Developed by: Grasshopper Manufacture
Published by: Warner Bros. Interactive Entertainment
Release date: June 12th (NA), June 13(Aus),Jun 14(JPN) June 15(Eur)
Genre: Action
A Suda action game while it is already being criticized for having a short length it may have decent replay value. I'm hoping it sells well due to unique gameplay. It is already having DLC costumes already coming for the Japanese version at least but without them is still a good game hopefully.
Heroes of Ruin
Platform: 3DS

Developed by: n-Space
Published by: Square Enix
Release date: July 17th (NA)...., June 21(Aus), June 15(Eur)
Genre: Action
A Square Enix game according to videos it seems to play fairly well with a top down perspective but it has shown to have some problems like does it have camera rotation and others. This is a game to look forward to review wise which will hopefully be great.
Resident Evil: Chronicles HD Collection
Platform: PS3

Developed and Published by: Capcom
Release date: June 26th (NA), June 27(Eur)
Genre: Railshooter
While the two games may have already been released for the Wii it does not mean this is a game to miss. With the improved HD graphics and the price of 26.99 it is well worth the money assuming you have the Playstation Move. With a dualshock it might not play as well or at all. Comes with Umbrella Chronicles and Darkside.
Steel Battalion: Heavy Armor
Platform: X-Box 360

Developed by: From Software
Published by: Capcom
Release date: June 19th (NA), June 21(Aus, Japan), June 22(Eur)
Genre: Mech Simulation
The world is stuck using Veritcal Tanks after the world loses computers for the most part. The customization promises to be deep but the Kinect controllers work well according to some reviews of the demo. The gameplay is more like Chromohounds then the faster pace Armored Core but promises to be a decent Kinect game.
Mentions
Spec Ops: The Line Most likely a generic shooter as the demo has shown. PS3, PC, 360
Persona 4 Golden JPN Release A great RPG being released for the Vita if you haven't played the PS2 version check it out. Vita
Metal Gear Solid HD Collection Pretty much a rerelease without Peace Walker Vita
Sins of a Solar Empire: Rebellion PC RTS was pretty good haven't played the more recent ones PC
