Only put 30k into a game project if you can definitely afford to lose that 30k! You should have low to very low expectations of returns on it, especially with little or no experience in the industry.

Hey guys. I was lucky enough to inherit some money and part of that money i would like to invest into a game project.

Congratulations. Might I suggest you pile it all in your back yard and set fire to instead? It will likely be a far more entertaining use of the funds and will have about the same net result.

Im lookin to put aprox about $30k-$40k

Is that a decent amount to create a decent project?

It depends on what you mean by "decent," but in all likelihood, no, that is not on it's own enough to create a decent project. Certainly not one with a reasonable likelihood of giving you any kind of return on your investment. It will likely get you the salary alone for a single developer (for how long depends on how skilled a developer), and possibly some overhead costs. It will go further if you're planning to invest it into a pre-existing project, but that's not the impression you're giving.

I currently dont have any ideas about what game or what engine or whatever im gonna do.

Now this is confusing. Are you going to invest that money (with the hope of return), funding somebody else to make a game, or are you going to use that money yourself to buy yourself the tools, technology, et cetera you need to make a game? They are very different things.

Game development is not a safe investment, especially if you are not very familiar with the industry. I strongly encourage you to take that money you've got and pay yourself with it instead: ensure your emergency fund is well-stocked, pay down all your debts, and put the rest aside for longer-term financial gain by maximizing your contributions to tax-free or tax-advantaged account instead. Any reasonable financial advisor can help you with this (and will probably also strongly caution you off making such an extremely risky investment as trying to fund a game development project as well).

Just a general question this is

First thing you need to do is determine your financial goal with this investment. What are you looking to accomplish by investing this money? Do you have a dream project you want to realize? Are you looking for a specific return on your investment?

The reality is that throwing $30-40k at a project is going to result in losing it. And especially so if you don't have any professional experience behind it.

While I agree with the general comments regarding financial investment, I can also add the following:

If you like games, you might want to invest only a smaller part of your money to help talented (and professional) indie teams. This has a very high risk, but I'll detail in a later post why I think it's reasonable.

(I removed the inappropriate part from my previous post.)

To further clarify my point: if he likes games, he should invest a small part of his money to a project he likes and finds convincing (financially and in other aspects as well). NO financial advisor can tell you what business to invest in without a serious risk. They will suggest you a portfolio, depending on how risky investion you want. But there will always be a "faith" factor. You can indeed lose all your money with it, but if anyone knew the recipe of what business to invest in, that person would be billionaire, have a Nobel-prize, and probably could rule the world. So the personal factor (and luck factor) is always there. If you don't invest at all to a very risky thing, your chance stays a guaranteed 0%.

So we should really know how much risk the OP is willing to take. This is what the financial advisor will first ask him, too.
