Oh, I guess the OP was asking about what real money would buy versus in game wealth.
Personally, I'd rather see this as a subscription - manditory or optional - than a possible pay-to-win game. I've played Battlestar Galactica Online, and while you COULD earn enough premium money in game to get whatever you wanted, the time to earn the same amount that you could by with real cash money could be days worth of grinding away. At least the best upgraded space-ships you could possibly get require you to earn special merits via PVP fights, but even those ships are prohibitively expensive to buy to upgrade to begin with. This pay-to-win method causes a lot of resentment among many members - especially those who've dumped months into the game to find someone a tenth of their level riding around in better ships.
SO, here's what I would do vs. here's what's more likely to happen in a more than less ideal situation.
Optional Subscriptions: Everyone would get the same chance to build up mechs, kit them out with gear, and earn experience, paying or not. Paying players would have a boost to overall C-Bill aquisition and/or discounts in the market, experience bonuses - say 5% faster experience gathering.
What subscribing would do is open up a variety of cosmetic changes from custom pilot ID's (nose art), different color lasers/effects, metallic color overlays for existing colors (so as not to lose the unit colors, just have them look more bad-ars) and bizarre colors for lone wolf mechs.
______________
With no subscription option, cash money could be spent on consmetics as the paragraph immediately above describes. It could buy up to a maximum of 5% bonus experience, and a maximum c-bill aquisition or market discount of 20%. It would also give you a certain amount of trade-in vouchers. These could be used to trade in existing gear or mechs for equal value mechs and parts or C-Bills rather than the typical gouging that would take place in a marketplace.
What cash money COULD NOT buy you is C-Bills, experience, gear, or mechs. While it would give you the perks of getting faster earnings in experience and c-bills, it should never allow for direct purchase of c-bills or experience. If this game is truly going to be fair to all, then no one, paying or not, should feel that they HAVE to pay to keep up with other players. Bonuses as described above would be acceptable because it means that the paying players would still have to play, earn loyalty, and bust their hump to get the ranks, xp, and C-bills they want which would help keep people from crying foul. After all, paying players are paying for the free players to play and should get something tangible for it.
Another option is stables: If, let's say, each player is normally limited to having 4 mechs in a stable; maybe the paying players could have extra slots in a stable, and/or extra total tonnage aloted for storing of salvaged parts, chassies, etc. for eventual building - rather than buying new or used mechs - from the market.
Conclusion: Make it an optional subscription for the above perks. Barring that, spending money on the game should keep fairness in mind .
If I am going to tell my friends about a free-to-play game, and I tell them that if you spend money, you'll be so much better off than others, many of my friends would look upon the game with suspition and doubt. Especially as I'm working to bring many of my friends with me from BSGO to MWO. The devs in BSGO have made it really tough on non-paying players. Likewise, because they already gouge the paying players to keep up their profits, the paying players stop paying and the devs can't afford to bring out anything new and the whole game and the players all suffer.
DEV'S, please consider an optional subscription over paying-to-win. PLEASE.
