Infinity is a great game - it is polar opposite to 40k... your list doesn't mean anything. I can even legally show you a fake list because some of my troops can pretend to be other troops. And if I have troops that can deploy by Airborne Deployment, they aren't even on the list!
Your strategy and tactics are everything. Every faction is virtually equal, although they all play very differently and most do have a steep learning curve. Basically you pick the faction with the miniatures you like the best and you win games with experience, not just by picking up the latest overpowered flavour and running a canned list from the interwebs.
Everything in the game is able to be killed by the most basic weapon (the rifle). It doesn't matter what you take to the fight, its all about how you use it. And the options are mind-boggling...
The game requires about 20 times the terrain of a usual 40k game - the weapons are extremely deadly and cover is your only hope. Swiss cheese ruined cathedral GW "terrain" need not apply... its less than useless in Infinity!
Corvus Belli makes incredibly detailed miniatures and releases at least 5 new ones every month (December release was 12 - 2x box set of 4, a TAG, and 3 singles, all for different factions... when you only need 9 or ten miniatures for a full 300 point army...
... are all you Tau players feeling a little neglected yet?)
Very, very nice looking minis. Though at 33% more than a Crisis Suit I don't think I'm buying in soon.
A Cutter TAG costs 117 points - of your 300 points available - its more like 6% of a Warhound Titan if you are trying to compare prices per percentage of an army!
TAG's are good, and a kick in the face when you first play against one, however they require a lot of orders to be viable and once you work out a strategy to defeat it they are rarely seen again. While you are Rambo-ing your Cutter up field, my panzerfaust Muyib linkteam have positioned some nasty surprises for you, and my HMG Ragik is turning your cheerleaders into pulp! All for the same points cost. (I play Haqqislam by the way.) An ADHL will make even quicker work of that TAG... and the Nomads can hack that baby in 2 seconds flat!
With the latest book, Paradiso, objectives have become even more important so you need to bring an engineer, a hacker, a baggage bot and a doctor to even stand a small chance of winning. There is hardly room for a TAG anymore. And there is no room for simplton "annihilate" missions either - playing a game to just kill the other guys army is sooooo last century.
If I suffer from a spell of analysis paralysis while playing Infinity, my answer is always "If this was a movie, what would I do?", and then I do it!
You can climb walls, set up ambushes, impersonate the other players figures, hack anything with an electronic pulse (even guided munitions!), use thermo-optic camouflage, holoproject yourself, smash through things, jump across yawning crevasses, parachute into enemy territory... every standard game is far more "cinematic" than GW wishes 40k could ever dream to be.
Please give Infinity a try. Just leave your 40K brain at the door and I know you will love it! The rules are free and there is an army builder on their website.
