Crysis wars and original crysis actually are the same price now. Its a bit strange tbh, ever since EA started origin they've been doing their pricing very strangely.
Currently customization is limited to choosing from a selection of variants(theres 256(not limited, just lucky) with more added all the time) with preset weapons, heatsinks, armor distribution, electronics, etc. And they use a pod system instead of crits. Mechlab isnt in yet, its planned though and development is still going strong (last patch was 5 new mechs, 3 new aeros, a vtol, a hovercraft and a tank, updates of that size are rare but theres new content every few months). Right now, theres enough variants for every mech and vehicle to cover basically every viable role. The fine tuning on the player's end is missing, definitely. There are some people who say the lack of a mechlab actually helps gameplay, i wouldn't agree but the lack of it hasn't had an impact as much as one might first assume. Mech loadouts in older mech games (and even MWO from what i've seen) often became homogenous, people all using a few set loadouts. With the variant system and the more diverse "needs" of the battlefield in MWLL, it seems like theres a much wider range of stuff being used out there. This is especially true with the lighter mechs. BA you can pick exactly what your loadout is (this is obviously the simplest though, as its essentially infantry), and more BA types (golem, etc) are actually in the works. Oh, and you can pick camos for your mechs (obviously very important).
the "limits" on stuff you take out are cbill related, rounds being 60 minutes usually means that the round based cbill system has a lot of time to work. The more you do, the more cbills you get in a game to spend on bigger stuff. You can die and buy what you bought in your life, or return to the hangar, sell your mech and buy something else with the money. often only quite skilled players can make it past medium/heavies (some mediums cost more than some assaults, blame the clan tech) giving lights and mediums use throughout the match. There's repair pads, APCs for ammo delivery that also spawn BA, and all that you can spend on too. On most maps there's also forward mech factories to fight over that let you build mechs there when they are under your control, and theres a few maps with airfields that you need to fight over if you want to get any air power at all. Some servers run puretech too, which means clans can only use clan tech and inner sphere can only use IS tech, and there's plenty of assets to support this.
The only infantry is the battlearmor/elementals, the ones from battletech of olde. I doubt anyone would want to play an armorless jetpackless dude with a dinky pistol in this sort of game though.
