ERA survival!

hiya guys! I'll be leas active because I've got school and things to do. but still I'll make talkies! . you have made a time machine but it's kinda unstable. so when you go in it you travel to a random era. (example:the Jurassic era) and you have to survive for 10 minutes in it. on the way surviving you can collect various and antique artifacts to sell when you go back in the present. you can use the cash to buy better equipment but your time machine becomes more unstable and sends you to more dangerous and chaotic eras. when your in an era you can meet a popular person in that era and fight them to erase them from history. you also have a risk machine next to your time machine. you can adjust it to make the time machine send you to more dangerous but high reward eras or adjust it to send you to safer but low reward eras. can you handle the constant historic pursuit or will you emerge Victorious?
