you could do that
OR you wait for the next free fly event which allows you to enjoy the alpha in all its glory for no cost with added benefits (often additional ships are unlocked during free fly). And if you cant restrain yourself from waiting please make sure to make up your mind within the refund period, at least its going to be risk-free that way for you.
Also forget about the "top end" remark as Star Citizen runs like a potato on high-end setups as well as actual potatoes and runs acceptable on potatoes and high-end set-ups...in short....nobody has a clue what makes SC runs smooth or bad but thats Star Citizen for you...not even the devs can tell you. You
have to use a SSD if you want to have any kind of tolerable loading/render times.
If you enjoy bugs and can laugh about comical situations resulting in SC gameplay then SC certainly is THE game for you. Doest offer much in regards to gameplay or depth tho...its even more shallow then ED right now but it DOES provide great screenshot material and allows you to enjoy vistas if you are into that kind of things.
Ah Havvk...thanks for the lulz man
