That's right in my case. I got to 353 with somewhat more play than I would ordinarily do. 20-30 of that came from mat trading that I did as an Arx experiment but the rest was the sort of thing I would ordinarily be doing. I considered going out late last night to cap it, but decided I'd rather be sleeping; 7/8ths of cap is enough.
I've got over 5000 Arx plus two skins and a nameplate that I had previously refused to buy because they were too expensive. I'm waiting for the basic paints to be reinstated for the Krait and then I'll buy another. I was amused when the cartographics data from my core mining survey trip exactly paid for my avatars spectacles, but apart from that I've paid for them all; the cheapest other thing I bought was 620 Arx so the earned Arx wouldn't have paid for any of it. I'm thinking about free Arx because it's a new mechanic that I'm interested in learning about. In a week or two, no more, I'll be ignoring it.
I'm also comparing prices in Arx, not GBP. I have no idea what a Holo-Me suit of clothes costs in real money, but I know it's horrendously expensive in Arx. I've put £4.99 into the account. After that I'm considering that 8820 Arx as the money I have to spend and reading the prices compared to that. It was exactly the same as going to the mall knowing I'd got £100 until pay-day, spending £30 here and there and then walking into the clothes shop, seeing that suits were over £150 and walking out again.
