As someone whose favorite games all share the "virtual world" aesthetic (Rez, Darwinia, etc.) I'm pretty starved for new games in that style and when they do come out, odds are stacked against them being any good (as the flat shaded, wireframe aesthetic is often used as a way to pass off amateur modeling and a lack of texture work as a stylistic decision)
Imagine my relief (and delight) when Tank Universal turned out to be one of the finest games in that vein that I've ever played. The handful of special "boss fight" type events were creative and memorable (rather than just larger than normal skirmishes) and the gameplay styles varied greatly over the course of the singleplayer campaign (CTF style, on-foot exploration, base building, destroying generators, etc) which is vital for keeping things interesting.
Here's what I want to see in part 2:
~More on-foot action! The serene, surreal exploration segment did a great deal to break up the action and make the world feel more "real" and fleshed out. Don't overdo these of course because after all I paid for a game called "tank universal", not "virtual sheep rider extreme".
~The ability to get out of my tank whenever I want, and enter other vehicles. Seriously, this would widen the gameplay possibilities immensely with the addition of the following:
~On-foot combat. Give us an upgradeable firearm, a tron-style disc that returns to you when thrown, and some kind of hacking tool for hijacking enemy tanks and other units. This would allow for missions where you sneak into enemy bases inside a hacked harvester. I'd also like to see some trench warfare. >:-)
~MORE immense, epic battles! By far the highlight of the game! And start us out on foot, as part of an infantry unit, so that we feel vulnerable, part of something larger than ourselves. Conceivably, many missions could require that we locate a vacant tank in the midst of a raging battle or hijack one for ourselves.
~Let us control turrets and dropships! Including the defense towers! That addition would bring TU very very close to being my dream game, something similar to Battlefield 1942 but set in a TRON style virtual world.
~ADD LIGHT CYCLES! If nothing else, please do this! It's the obvious addition and would make for a pleasant surprise to break up the tank gameplay partway through. They could also be used as a base-building unit later, to lay down walls (at the cost of crystal shards) that would impede enemy tanks and require several shots to destroy.
~Expand base building, and give us more control over it. I'd like to build generators and force fields for instance. And in the overview mode that you build the base from, allow the player to command infantry units and tanks, as well as telling dropships carrying reinforcements where to set down. Pillboxes would be a good idea, allowing infantry units some strong cover and providing an alternative to turrets and defense towers that can be placed anywhere (but which are also easier to destroy?)
~SECONDARY FIRE FOR THE TANK. I saw someone else suggest this and it was spot on. Even if it's just that laser machinegun dealie that the light armor units pester you with. It's a must if there's to be infantry combat.
~Less "Real world" cinematics. I found them corny and they detracted from the experience. Or, if you must add them, have the plot deal with a cyber-war between the US and China or something similar. I'd rather watch that than "the adventures of an old man playing videogames."
~Larger maps! I'd love truly vast battlefields to fight on, especially if the gameplay is to become more sophisticated.
~Allow us, in the singleplayer campaign, to (briefly) pilot one of those large floating battle cruisers. For real this time. It was pretty anticlimactic in TU1 when the most use blue team got out of the cruiser was as a battering ram. I want to see a battleship captured and used against Gorgon forces!
That's all I can think of. Once again, congrats on an amazing game. I'm eagerly awaiting part 2 with money in hand.
