This is a magazine print review, so I will not scan/copy the article verbatim. I will post some choice quotes.
Taken from the August 2013 issue of PCPowerPlay Australia. They review Hawken in the same issue and give it 7/10. The reviewers cites having played Earthsiege 2 and MechWarrior 2.
Quote
"If a developer is confident enough in its product that it will take your money, it's our job tell you if they deserve it."
"For first timers... Mechwarrior Online presents a solid wall of complexity. It's only with time that holes can be poked in it's crumbling mortar, rays of understanding shining through."
"The patcher loads an obtuse launcher page filled with a kaleidoscope of bad design. Colour and text are splayed everywhere, so it's not immediately clear that the game itself has loaded."
"the key bindings screen presents a bewildering array of things any given mech can do, and the player's hope of remembering them is proportional to the amount of game time they are willing to spend learning. Arguably, as a light simulation, this is as it should be."
"There is definitely a team focus, rather than an individual free for all."
"While the slower pace of the game may suit some, for me it felt a little sluggish to be something enuinely exciting or overly enjoyable."
"Thankfully, it doesn't feel as paying players have an overbearing edge."
"For a game proudly built on the power of CryEngine 3, it also leaves something to be desired in its visual fidelity. Textures from the landscape to the mech pilot are muddy, weapons fire and damage effects lack punch, and while the cockpit and other mechs look okay, it's disappointing."
"There's also the problem of scale. Trees, landscapes, buildings all appear small. ... In order to give the sense of the mech's size, the developers have effectively minaturised the surroundings.
Playing in this environment feels more like you're a regular size human stumbling through an architect's concept model for a new city business park, national park, or industrial complex (depending on the map)."
"It is a fundamental failure to the sensation of piloting a giant robotic machine of war and destruction."
"It requires a hefty time investment to learn, to customise mechs and pilots simply to get the most out of it. This is not to say it's bad... it's just an acquired taste." 6/10
