Is making everything the company owns as collateral normal as well?
No, but it's not like CIG has all that much of value to put up, and chances are that a bank would classify them as a very risky venture, making the credit rating of what they can offer rather low. So requiring “everything” for even a fairly small loan wouldn't be all that surprising.
As a bonus, it might also introduce the first proper pledging in this whole venture.
Oh, and as someone pointed out, there's this funny bit at the end:
Charge Papers said:24. LICENSE
24.1 The Chargee [Coutts & Co.] hereby grants the Chargor [CIG UK] an exclusive license, revocable only in accordance with Clause 24.2, to develop, produce, exploit and otherwise deal with the Game.
24.2 The Chargee may terminate the license granted persuant to Clause 24.1 above upon the happening of an Event of Default which remains unremedied on the date falling 60 days after the Chargee has given written notiec the Chargor of such Event of Default.
Translation: Coutts now owns the game. CIG may develop it if they keep paying their bills within 60 days of Coutts asking for the cash. Otherwise, snip-snip. CIG is now leasing the rights to develop the game they were given $150M+ to develop.
